16. ∠2 = 53° because it is supplementary.
- You are given the measurement of ∠1, which is 128°. From the picture you can see that ∠1 and ∠2 combined equal 180° (they are supplementary angles).
- So to find ∠2, simply subtract 128° from 180°. The answer is 53°.
------------------------------------------------
17. 12° because it is vertical.
- Vertical angles, like 48° and 4x in the image, are always equal.
- So if 4x = 48°, then you can divide both sides to get x = 12°.
Answer:
y=0.76
Step-by-step explanation:
5-8/3 = 3y
(5-8/3) x 3 = 3y x 3
6.9=9y
9y=6.9
y=6.9/9
y=0.76
Answer:
8 in²
Step-by-step explanation:
The area of a triangle is always base times half height. Since this triangle has a 90° corner, the vertical 4 inch is also the height.
So area is 4*4/2 = 8
