Answer:

$x = 24$

Step-by-step explanation:

Sum of the interior angles in the triangle is 180 degrees

So,

$72 + 64 + 4x +20 = 180\\$

Now solve for x

$72 + 64 + 4x +20 = 180\\\\156 + x=180\\x=180-156\\x=24$

hope this helps you

please let me know if you have any other questions :-)

We know, sum of all angles of a triangle is 180°.
Therefore, by the problem

72 + 64 + (4x+20) = 180

or, 156 + 4x = 180

or, 4x = 180 - 156

or, 4x = 24

or, x = 24 ÷ 4 = 6

<h3>Your answer is 6.</h3>

The area of a rectangular painting is 5/8 square yard. The width is 3/4 yard. What is the length of the painting?

vfiekz [6]

Answer:

The answer is

<h2> $\frac{5}{6} \: \: \: \: yards \\$ </h2>

Step-by-step explanation:

Area of a rectangle = length × width

Since we are finding the length of the rectangle

$length = \frac{area}{width} \\$

From the question

area = 5/8 square yards

width = 3/4 yard

So we have

$length = \frac{5}{8} \div \frac{3}{4} \\ = \frac{5}{8} \times \frac{4}{3} \\ = \frac{5}{2} \times \frac{1}{3}$

We have the final answer as

$\frac{5}{6} \: \: \: \: yards \\$

The lines are parallel. Find the slope-intercept form of the equation y₂.

Bas_tet [7]

Since the lines are parallel and you know the slope of $y_{1}$ is -2, you know the slope of line $y_{2}$ will also be -2. You can see on the coordinate grid that line $y_{2}$ crosses the y-axis at -1. When you piece all of these facts together into slope-intercept form you get $y_{2}$ = -2x - 1.
