Answer:
using trigonometric ratio sin, which is
sin[tex]\alpha[/tex]=opp/hyp to mean opposite/ hypotenuse
sin 40°= x/9
multiply both sides of this by 9 to remove the 9 in the side we have x, we will have
sin 40°/9=x
sin° 40 =0.7451
so x= 0.7451/9
which is
x= 0.0827888888
to give it in 3 decimal places, the answer will be 0.083 since 7 is the fourth number and is more than five, we add 1 to the 2 making it 3

Find the volume of the triangular prism to the right
Answers
Answer:
V = 567 ft³
Step-by-step explanation:
V = Bh
[note: a capital 'B' represents the area of the base]
The right triangle is the triangular prism's base.
Because the triangle's height (9 ft) and it's base are the same value (9 ft), we can solve to find the area.
We can identify the base easily because the base and the top of the prism are exactly the same shapeArea of triangular base:
A = [tex]\frac{bh}{2}[/tex]
A = [tex]\frac{1}{2}[/tex] (9 ⋅ 9)
A = [tex]\frac{1}{2}[/tex] (81)
A = 40.5
We have 'B' for the triangular prism's formula, so next we need 'h'. 14 ft is provided as the prism's height, so we just need to multiply 40.5 and 14 for our answer.
Volume of triangular prism:
V = Bh
V = (40.5)(14)
V = 567 ft³

Mel is 7cm less then her grandma's height. Her brother is 11cm taller then his grandma. Together height total 502 cm. What are their heights?
Answers
Answer:
Mel's height is 159cm, her brother's height is 177cm and their grandma's height is 166cm.
Step-by-step explanation:
Let the grandma's height be g cm.
Mel's height= (g -7) cm
Brother's height= (g +11) cm
Total height
= Mel's height +brother's height +grandma's height
= g -7 +g +11 +g
= (3g +4) cm
Given that their total heights is 502 cm,
(3g +4) cm= 502 cm
3g +4= 502
3g= 502 -4 (-4 on both sides)
3g= 498
g= 166 (÷3 on both sides)
To find their heights, substitute g= 166 back into the expressions.
Grandma's height= 166cm
Mel's height
= 166 -7
= 159cm
Brother's height
= 166 +11
= 177cm
The length of a rectangle is 7 cm longer than its width.
The area of the rectangle is 120 cm².
What is the width of the rectangle?
Enter your answer in the box.
Answers
Answer:
length = 15 width = 8
Area 15x8 = 120
Step-by-step explanation:
L = length
W= width
L = W + 7 (width plus7)
Area = W x L
Area =W (W+7)
Do the distribution:
120 = W ² + 7W
Subtract 120 on both sides
W + 7W -120 = 0
Factor it
(W + 15)(W - 8) = 0
W = -15 or W = 8
8 is used for W
L = W + 7
L = 8+7=15
Length = 15
Width =8.

The perimeter of a rectangle is 13 cm and its width is 2 ¾ cm. Find its length in cm.
Answers
Answer:
length = 3 3/4
Step-by-step explanation:
13 = 2(2 3/4) + 2l
13 = 2(11/4) + 2l
13 = 22/4 + 2l
52/4 - 22/4 = 2l
30/4 = 2l
30/4 ÷ 2 = l
30/4 x 1/2 = l
30/8 = l
length = 15/4 or 3 3/4

D. Segments JI and HG are parallel.

C. Points F, J, and H are collinear.
Step-by-step explanation:
Given
See attachment for triangle
Required
Which statement is false
Options A, B and D are true while C is false.
Two points are said to collinear if a straight line can pass through them.
From the attached triangle, we can see that a straight line cannot pass through F, J and H.
Hence, they are not collinear.
Since the statement is false, then it cannot be used as part of the proof.

Find the area of the given trapezoid.
Answers
240 is the answer you're looking for!
Step-by-step explanation:
To find the area, spilt the trapezoid into 3 shapes.
2 triangles (at the ends) and 1 rectangle (the center).
Let's start with the rectangle, the formula for rectangle area is:
[tex]l*w=A[/tex]
The length of the rectangle is 12, the width is 20. Add the numbers in:
[tex]12*20=A[/tex]
Solve:
[tex]12*20=240[/tex]
The area of the rectangle is 240. Now solve for the Triangles.
The formula for finding the area of triangles are is:
[tex](L*W)/2[/tex]
The length of the triangle is 12. To find the width subtract 20 from 30.
L = 12, W = 10. Add in the numbers.
[tex](12*10)/2 = A[/tex]
Use order of operations to solve, start with parenthesis:
[tex]120/2=A[/tex]
Rember to divide it by 2 because a triangle is half of a rectangle.
[tex]60 =A[/tex]
Since there are two identical triangles, you don't need to solve for the other
Now, add the areas together:
[tex]60 + 120+60=A[/tex]
Then solve:
[tex]180+60=A[/tex]
[tex]240=A[/tex]
The correct answer is 240.

A rectangle has vertices at: A(0, 0), B(0, 9), C(4, 9), D(4, 0) What is the perimeter of the rectangle?
Answers
Answer:
Rectangle Perimeter = 26
Step-by-step explanation:
Rectangle ABCD , Length = parallel horizontal sides are AB & CD, Breadth = parallel vertical sides = BC & AD
AB segment joining A (0,0) - B (0,9) = 9 units. CD joining C (4, 9) & D (4,0) = 9 units. So, Length = 9 units
BC segment joining B (0,9) - C (4,9) = 4 units. AD joining A (0,0) - D (4,0) = 4 units. So, Breadth = 4 units
Perimeter of rectangle = 2 (Length + Breadth)
= 2 (9 + 4)
= 13 x 2 = 26

Step-by-step explanation:
You are smart don't say you're not. :)
Answer:
Surface Area is 148 cm^2
Your Volume will be 120 cm ^3
Step-by-step explanation:
Surface Area you get by getting the area of each of the 2 dimensional shapes, the formula to get the surface area for a rectangualr prism is 2(wl+hl+hw), so you would plug in 2((5(6))+((4(6))+(4(5)) which will give you 2((30)+(24)+(20)) which will then give you 2(74) and the final answer will be 148 cm^2
The formula for Surface Area is w(l)(h) so in this case it will be 5(6)(4) which will be 30(4)= 120 cm^3
