Answer:

x = -7

Step-by-step explanation:

Simplifying

5x + 130 = 8x + 151

Reorder the terms:

130 + 5x = 8x + 151

Reorder the terms:

130 + 5x = 151 + 8x

Solving

130 + 5x = 151 + 8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8x' to each side of the equation.

130 + 5x + -8x = 151 + 8x + -8x

Combine like terms: 5x + -8x = -3x

130 + -3x = 151 + 8x + -8x

Combine like terms: 8x + -8x = 0

130 + -3x = 151 + 0

130 + -3x = 151

Add '-130' to each side of the equation.

130 + -130 + -3x = 151 + -130

Combine like terms: 130 + -130 = 0

0 + -3x = 151 + -130

-3x = 151 + -130

Combine like terms: 151 + -130 = 21

-3x = 21

Divide each side by '-3'.

x = -7

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)
Eduardwww [97]

Given:

The figure of a right triangle. PO=12,m\angle O=y^\circ and perpendicular = 12.

To find:

The measure of angle y.

Solution:

In a right angle triangle,

\sin\theta=\dfrac{Perpendicular}{Hypotenuse}

In the given right angle triangle,

\sin y^\circ=\dfrac{7}{12}

y^\circ=\sin ^{-1}\dfrac{7}{12}

y^\circ=35.685335^\circ

y^\circ\approx 35.69^\circ

Therefore, the measure of angle y is y^\circ =35.69^\circ.
