Answer:
∠ 1 = 94°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
130° is an exterior angle of the triangle, then
∠ 1 + 36° = 130° ( subtract 36° from both sides )
∠ 1 = 94°
Answer:
x²+x-30
x=5
Step-by-step explanation:
The equation is
(x+3+x-1)/2 × x=30
x²+x-30 (it's the quadratic equation)
x²+6x-5x-30=0
x(x+6)-5(x+6)=0
(x+6)(x-5)=0
x=-6
x=5
It's impossible for Length to be negative
So x=5
