I DONT UNDERSTAND HELP <br> Find the values of the variables<br><br> (Simplify your answers )
SVETLANKA909090 [29]

Answer:

x=88 (alternative angles)

y=31 each

v=41 (alternative angles)

w=20 (alternative angles)

Step-by-step explanation:

for y:

we add all the angles got therefore,

20+41+88+y+20+41+88+y=360(because total angle in a quadilateral is 360°)

298+2y=360

2y=360-298

2y=62

therefore y=62/2=31° for each y

Solve for a a^2+17=42?
grandymaker [24]

We are given the following equation:

a^2+17=42

Subtract both sides by 17

a^2=25

Take the positive/negative square root of both sides

a=\pm5

This should be your answer. Let me know if you have any questions, thanks!
