Find the measure of the missing angle. ( me) with work

TO FIND THESE MISSING ANGLES WE USE THE 2n-5(90) formula. n represents the amount of the sides.

Then we add the given angles and subtract it from the value of the shape.

3. The missing angle is 159°

2n-5(90)

2(5)-5(90)

10-5*90=450°

119+89+83=291°

450°-291°=159.

4. The missing angle is 69°

2n-5(90)

2(4)-5(90)

8-5*90=270°

122°+79°=201°

270°-201°=69°

HOPE THIS HELPS!

HAVE A GR8 DAY! ;-)

whats the question?

step-by-step explanation:

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
