Answer:

x= 7

Step-by-step explanation:

Theorem:  The sum of the angles of a triangle is 180

Memorize that theorem

8x - 9 + 63 + 70 = 180

8x + 124 = 180

8x = 56

x= 7

Alexandra [31]

Answer:

Height is 7m

Step-by-step explanation:

B = 10 feet area = 35 feet 2 Find the height of the triangle.

Area of triangle = 1/2 b×h

Can someone help me on this
barxatty [35]

A) as the exponent decreases by one, the number is divided by 5

B) as the exponent decreases by one, the number is divided by 4

C) as the exponent decreases by one, the number is divided by 3

D) 4⁰ = 4 ÷ 4 = 1

    4⁻¹ = 1 ÷ 4 = \frac{1}{4}

    4⁻² = \frac{1}{4} ÷ 4 = \frac{1}{16}

E) 3⁰ = 3 ÷ 3 = 1

    3⁻¹ = 1 ÷ 3 = \frac{1}{3}

    3⁻² = \frac{1}{3} ÷ 3 = \frac{1}{9}
