Answer:
D. (4,3)
Step-by-step explanation:
I calculated it logically
Common factor of 20= 1,2,4,5,10.......
common factor of 35=1,5,7.............
so here we find that 1 and 5 r the common factors
but the GCF of 20 and 35 is 5
so,
by using GCF the distributive property is : 5(4+7)
X = 8
y = 40
the two base angles are equal to each other so you would do 5x = 40 and solve for x
a triangle has 180 total degrees. 40*2 = 80
180 - 80 = 100
2y + 20 = 100
2y = 80
y = 40
