Answer:

∠ B = 80.5°

Step-by-step explanation:

Since AB = AC then the triangle is isosceles with base angles congruent, so

∠ B = ∠ C , then

∠ B = $\frac{180-19}{2}$ = $\frac{161}{2}$ = 80.5°

Consider triangle ABC where AB=X+5, BC=X-2, area is 30cm squared. Find X by solving X^2+3X-70=0, and find the perimeter.

Answer:

What the hell AC is not given so you can't find the Perimeter

Step-by-step explanation:

x^2+3x-70=0

(x-7)(x+10)=0

x-7=0

x+10=0

x=-10

AB=x+5

AB=12

AB=-5

BC=x-2

BC=5

BC=-12

Area of ABC = 30cm2

Perimeter of ABC = AB+BC+AC
