(x² + 16x)² = 17²

√x² + 16x)² = √17²
(x² + 16x) = (+-)17
1st equation: x²+16x-17 = 0
2nd equation:x²+16x+17 =0
Let's solve these 2 quadratic equation:
1st equation x' =1 & x" = - 17
2nd equation x'= (-8+√47) & x" =(-8-√47)

Solve for x <br><br> (5x-1) 8x

trapecia [35]

Answer:

x = 7

Step-by-step explanation:

Given is the figure of a kite.

Opposite sides are equal... (given)

Since, measures of the angles opposite to equal sides are equal.

Also, diagonals of a kite interests at right angles.

Therefore,

$8x \degree + (5x - 1) \degree + 90 \degree = 180 \degree \\ \\ (8x + 5x - 1) \degree = 180 \degree - 90 \degree\\ \\(13x - 1) \degree = 90 \degree\\ \\ 13x - 1 = 90 \\ \\ 13x = 90 + 1 \\ \\ 13x = 91 \\ \\ x = \frac{91}{13} \\ \\ x = 7$

Therefore,
