Answer:
x = 13
Step-by-step explanation:
Since AB = AC , then Δ ABC is isosceles
So the base angles are congruent , both 2x + 15
The sum of the 3 angles = 180° , then
2x + 15 + 2x + 15 + 98 = 180
4x + 128 = 180 ( subtract 128 from both sides )
4x = 52 ( divide both sides by 4 )
x = 13
Factor each
4k=2*2*k
18k⁴=2*3*3*k*k*k*k
12=2*2*3
GCF=2
the greatest common factor is 2
You can conclude that AE = DE because the triangles are about equal
