I believe the answer is C = 20
The measure of angle D is 39 degrees.
Since it’s an isosceles triangle, the two unmarked angles are equal. Since you know there are 180° in a triangle, subtract 102° from 180° to get 78°. Then, cut that in half since you need to divide it equally among the two remaining angles.
What is it? Put the picture up
1. false
2. 50,00
3. about 250
4. True
5. 0
6. 1/13
7. 0.08
8. 25%
9. 1/3
10. 1/2
I could be wrong on some of these though
(0.85x - x/x)*100= (0.85 - 1)*100= 0.15*(100)= -15
