Answer:

x = 28

Step-by-step explanation:

angle 1 and angle 2 are complementary (their sum is 90°)

x + 5 + 2x + 1 = 90 add like terms

3x + 6 = 90 subtract 6 from both sides

3x = 84 divide both sides by 3

9x²+7x-2=0 find it's real root

lbvjy [14]

The Given Quadratic Equation is bx + c = 0

$\sf \: so \: \: \: \: \: a = 9 \: \: \: \: \: \: \: \: \: \: b = 7 \: \: \: \: \: \: \: \: c = - 2$

We Know That Determinant (D) = b²– 4ac

$\sf \: (D) = {7}^{2} - 4 \times 9 \times - 2$

$\sf \: (D) = 49 - 36 \times - 2$

$\sf \: (D) = 49 + 72$

$\boxed{ \underline \color{skyblue}{\sf \: (D) = 121 > 0}}$

The Determinant of The Equation is Positive So,

The Expression Contains Real Root.

Does anybody know how to solve these? 10 and 11.

Anarel [89]

10. The compass length (3 inches) represents the radius of the circle that is about to be drawn.

We know an equation for the area of a circle is pi x r^2

So lets use that equation

A (circle) = pi x 3^2 = pi x 9 = 28.3 square inches

and 11 is one fourth
