As in this figure two sides of triangle are equal so angle A=B because angle opposite to equal sides are equal so
60+x+x= 180
60+2x=180
2x= 180-60
2x=120
x=120/2
x=60
Therefore B,C is 60
Answer:
a = 
Step-by-step explanation:
Given
G = 4ca - 3ba ← factor out a from each term on the right side
G = a(4c - 3b) ← divide both sides by (4c - 3b)
a = 
9+9+7+7=32 :) you add each side up
9514 1404 393
