What is the measure of y

y = 156 degrees

Step-by-step explanation:

90-66=24

180-24= 156

y is 156°.

Step-by-step explanation:

We know ∠FED is 66°, and ∠FED & ∠DEB (or z) equal 90° degrees. That means ∠z is 24° degrees as is ∠x, since it is adjacent to ∠z. ∠x and ∠y are supplementary, which meant they equal 180°. Subtract 24° (∠x's measurement ) from 180° to get your final answer of y being 156°.

I hope this helps!~

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.  

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
