She cant make any because she only has 34 but she needs 112
Answer:
225°
Step-by-step explanation:

Answer:
BC = 34
Step-by-step explanation:
Given that ∠B = ∠C then the triangle is isosceles.
Thus AB and AC are congruent, that is
4x - 8 = 2x + 12 ( subtract 2x from both sides )
2x - 8 = 12 ( add 8 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
Hence
BC = 3x + 4 = (3 × 10) + 4 = 30 + 4 = 34
Answer:
9
Step-by-step explanation:
it's an isosceles right ∆.
so (9√2)^2 = 81*2= 162 = 2s^2
let x=y=s
s^2 = 81
s = 9
