Answer:
x=45°
Step-by-step explanation:
The 160° plus the unlabeled angle to the left of it are supplementary, meaning when added they equal 180°. The unlabeled angle will therefore be 20°. The angle across from the 20° will also be 20°. 115° + 20° = 135°. Now all that is left on the top half is x.
180° - 135° = 45°
Divide y by x, in this case 144 gets divided by 9, and you have your answer
D. 0.07. the negative exponent which is two indicates the number of zeros in the standard form. and the 7 indicates the first number in the standard form
