WILL GIVE BRAINLIEST ANSWER TO CORRECT CHOICE HURRY HURRY. :D
Answers
Answer:
C) m∠A = 66
Step-by-step explanation:
The value of ∠ A for the given isosceles triangle is 66°. Option (C) is correct.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
In the given triangle ABC,
Side AB = AC, Angle C = 57°.
Since, two sides of a triangle are equal implies that,
Triangle ABC is an isosceles triangle.
Therefore,
∠ B = ∠ C = 57°
Also, sum of all angles of a triangle is 180°,
∠ A + ∠ B + ∠ C = 180°
∠ A + 57 + 57 = 180
∠ A + 114 = 180
∠ A = 66
The value of ∠ A is 66°

Substitute the given values:
A= 4
B= 3
C= 2
5(a+b)-3(b+c)
5(4+3)-3(3+2)
Add the numbers:
5(7)-3(5)

In the figure shown, triangle RST undergoes reflections across two line. R''S''T’’ is the final image of RST
Triangle RST is first reflected across the line x=0 and then across line
a. x=0
b. y=0
c. y=x
d. y=-x
Answers
======================================================
Explanation:
Point T is at (-2,1)
When we reflect it over the line x = 0, aka the y axis, we use the rule [tex](x,y) \to (-x,y)[/tex] so T(-2,1) becomes T ' (2, 1). The x coordinate flipped in sign, while the y coordinate stays the same.
Then the final transformation is reflecting over y = -x using the rule [tex](x,y) \to (-y, -x)[/tex]. Therefore, the point (2,1) moves to (-1, -2) which is where T'' is located in the diagram.
You apply the same two transformations for the points R and S to get R'' and S'' respectively.
Note: A composition of two reflections, where the lines of reflection aren't parallel, form a rotation. In this case, we have a 90 degree counterclockwise rotation when going from triangle RST to triangle R''S''T''.

Multiply both sides by 3.

Zack measured a rectangular garden at the park. The longer sides each measured 15 feet and were 3 times longer than the shorter sides. If Zack walked all the way around the garden, how far did he walk?
Answers
Given:
The longer sides of a rectangular garden = 15 feet
It were 3 times longer than the shorter sides.
To find:
The total distance covered by Zack if he walked all the way around the garden.
Solution:
Let the shorter side be x.
Longer side = 15 feet
According to given equation, longer side is 3 times longer than the shorter sides.
[tex]15=3x[/tex]
Divide both sides by 3.
[tex]5=x[/tex]
So, the measure of shorter side is 5 feet.
The total distance covered by Zack if he walked all the way around the garden is the perimeter of the garden.
Perimeter of rectangular garden is
[tex]Perimeter=2(length +width)[/tex]
[tex]Perimeter=2(15 +5)[/tex]
[tex]Perimeter=2(20)[/tex]
[tex]Perimeter=40[/tex]
Therefore, the total distance covered by Zack is 40 feet.
Nathan bought a pair of boots for $79.95 and 2 shirts for $19.99 each. The sales tax is 7%. How much did Nathan pay for all the items, including tax?
Answers
Answer:
Nathan paid $128.3251 for all the items, including tax.
Step-by-step explanation:
∵ Nathan bought a pair of boots for $79.95
∵ Nathan bought 2 shirts for $19.99 each
→ Find the total price of them
∴ The total price of the items = 79.95 + 2(19.99)
∴ The total price of the items = 79.95 + 39.98
∴ The total price of the items = $119.93
∵ The sales tax is 7%
→ That means we will add 7% of the total price to the total price
∴ Nathan paid = 119.93 + 7%(119.93)
∵ 7% = 7 ÷ 100 = 0.07
∴ Nathan paid = 119.93 + 0.07(119.93)
∴ Nathan paid = 119.93 + 8.3951
∴ Nathan paid = $128.3251
∴ Nathan paid $128.3251 for all the items, including tax.

A serval, an African wildcat, leaps high above the ground to pounce on its prey. The height of the serval above the ground in relation to the horizontal distance it travels, both measured in feet, is modeled by the given function.
What does the domain of the function represent in this situation?
A.
the horizontal distance the serval travels during its leap
B.
the height of the serval along the path of its leap
C.
the horizontal distance at which the serval reaches its maximum height above the ground
D.
the maximum height the serval reaches above the ground
Answers
Answer:
A. the horizontal distance the serval travels during its leap
Step-by-step explanation:
In this situation, the height along the path that the serval leaps is represented on the y-axis (range value), as against its corresponding horizontal distance on the y-axis (domain value) during the course of its leap.
Therefore, in this situation, the the horizontal distance the serval travels during its leap is the domain of the function.

Step-by-step explanation:
It's very simple actually!
All you need to do is subtract 32:
58 - 32 = 26
Then divide:
26 ÷ 2 = 13
13 is Rudy's age. Let's find her father's age!
We then add 32 back to 13:
32 + 13 = 45
And there you have it!
