Answer:
Step-by-step explanation:
75+3x+(4x+10)
ok look at the triangle 2 sides are congruent means 2 angles are congruent
that means that 75 and 3x are congruent
75=3x
divide by 3 both sides
x=25
75+75=150
30=4y+10
y=5
13x + 3 = D
11x + 6 = C
10.9
4 1/2 plus 6 2/5=10.9
4
You must simply combine the two
