Question

I Need Help on this Math Problem!

Answer 1

Step-by-step explanation:

1. vertically opposite angles are the same

b = 42

360 - (42 + 42)

360 - 84 = 276

276 ÷ 2 = 138

c = 138

2. angles in a triangle sum to 180

right angles = 90

180 - (90 + 62)

180 - 152 = 28

angle S = 28

3. 1st question no, unless one angle is given a number. angles are the same vertically opposite so the other 2 angles are also vertically opposite but angle is different size but by adding the 2 different angles, make them supplementary as they sum to 180. 2nd question yes. you could have 4 right angles.
