If angle P measures 50 degrees, what is the measure of angle Q? A).50°
B).130°
C).40°
D).180°

B) 180°

Step-by-step explanation:

Angle P and Q forms a straight line which means they add up to 180 degrees.

So angle P is 50 degrees then we need to find it's supplement.

Using the equation 50 + x = 180 we can solve for x to find the supplement.

50 + x = 180   subtract 50 from both sides

-50        -50

x = 130

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
