likoan [24]

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.

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
