We know that, Two angles are said to be complementary, if the sum of their measures is 90°.

According to the Question,

⇒ ∠ABD + ∠DBC = 90°

⇒ (2x + 30)° + (3x + 20)° = 90°

⇒ 2x + 30° + 3x + 20° = 90°

⇒ 5x + 50° = 90°

⇒ 5x = 90° - 50°

⇒ 5x = 40°

⇒ x = 40°/5

⇒ x = 8

So, the measure of each angle will be,

⇒ ∠ABD = (2x + 30)°

= 2 × 8 + 30°

= 16 + 30°

= 46°

⇒ ∠DBC = (3x + 20)°

= 3 × 8 + 30°

= 24 + 30°

= 54° ▄▄▄▄▄▄▄▄▄▄▄▄▄▄

Page 3 - the y-intercept would remain at 5 and the slope would be 3 times the upward slope.

Page 5 - the y-intercept would remain at -2 and the slope would be 1/4 instead of 5

Step-by-step explanation:

In point slope form the slope and y-intercept can be read directly from the equation.

y = mx + b where m is the slope and b is the y-intercept.

Answer:

X (2, 1)

Y (2, 3)

W (5, 5)

Step-by-step explanation:

The current points are:

X (-2, -1)

Y (-2, -3)

W (-5, -5)

Now, after rotating 180 degrees around the origin, here is what points Y, Y, and W would look like:

X (2, 1)

Y (2, 3)

W (5, 5)

Plot these new points on the graph, and you'll have a new figure which will be rotated to 180 degrees.

I have also provided you with a graph, showing both, the original and the rotated version, below.

Find the measure of the missing angle of each

Answers

Answer:

? = 120, ? = 145, respectively

Step-by-step explanation:

? + 60 = 180

? (+ 60 - 60) = 180 - 60

? = 120

35 + ? = 180

(35 - 35) + ? = 180 - 35

? = 145

Here is a room with two lasers. Your goal is to get to the opposite side of the room. However there is a catch; if you do not stay equidistant from each laser, you will be blasted. Describe in a Word document how you would find the straight-line path across the room. Be sure to use correct geometric terminology from what you have learned so far.

Answers

Step-by-step explanation:

we would calculate the line of sight between the 2 lasers.

then we would create a line that goes through the middle point between the 2 lasers and is perpendicular to the line between the lasers. if we are lucky, then "You" is on the same perpendicular line. if not, we need to shift our starting point to a point where the perpendicular line hits the wall of the room.

by following that perpendicular line precisely, we we always have the same distance from both lasers.

13RHS

HP

Answer:

see explanation

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1

Consider left side

(2sinx + 3cosx)² + (3sinx - 2cosx)² ← expand parenthesis using FOIL

= 4sin²x + 12sinxcosx + 9cos²x + 9sin²x - 12sinxcosx + 4cos²x

Collect like terms

= 13sin²x + 13cos²x ← factor out 13 from each term

= 13(sin²x + cos²x)

= 13 × 1

= 13

= right side , thus proven

Find m<1 if <1 is complementary to <2, <2 is supplementary to <3, and
m<3 = 126

Answers

Answer:

∠ 1 = 36°

Step-by-step explanation:

Supplementary angles sum to 180° then

∠ 2 + ∠ 3 = 180° , that is

∠ 2 + 126° = 180° ( subtract 126° from both sides )

∠ 2 = 54°

Complementary angles sum to 90° , then

∠ 1 + ∠ 2 = 90° , that is

∠ 1 + 54° = 90° ( subtract 54° from both sides )

∠ 1 = 36°

so i'm struggling with a different problem this time. 5p - 9 = 2p + 12. (keep in mind i am an 8th grader in a high school algebra 1 class so i'm pretty clueless)

Answers

Solution :

5p - 9 = 2p + 12

5p - 2p = 12 + 9

3p = 21

p = 21 ÷ 3

p = 7
5p - 9 = 2p + 12
5p - 9 - 2p = 12
3p - 9 = 12
3p - 9 + 9 = 12 + 9
3p = 21
3p/3 = 21/3
p = 7

Amaya wants to jog 8 miles this week.She jogged 2 1/2 miles on Monday and 3 2/5 miles on wednesday. How many miles does Amaya still need to jog?

Answers

Answer:

2 1/10 miles.

Step-by-step explanation:

8 - (2 1/2 + 3 2/5)

= 8 -  (5/2  + 17/5)

= 8 - (25/10 + 34/10)

= 8 - 59/10

= 80/10 - 59/10

= 21/10

= 2 1/10 miles.
