Step-by-step explanation:
81/90 + 9/81 = 90/90 = 1
"In an isosceles triangle two angles are the same and the third is different. However, the angles in the triangle must add up to 180. If the 100 degree angle was one of the 2 identical angles, then the angles in the triangle would add up to more than 200. Because of this the 100 degree angle must be the different angle."
Answer:
8) v = 312
9) s = -12/13
Step-by-step explanation:
8) Multiply left and right by -14, then you get
v-18 = -21*-14
v-18 = 294
Add 18 left and right:
v = 294 + 18
v = 312
9) Add 26 left and right
-13s = -14 + 26
-13s = 12
Divide left and right by -13
s = -12/13
