<h3>In question a, </h3>

Interior angles are supplementary

So, x+50 = 180

x = 180-50

<h3><u>x = 130</u></h3>

Alternate angles are congruent

x = y = z

<h3><u>y = 130</u></h3><h3 /><h3><u>Z</u><u> </u><u>=</u><u> </u><u>130</u></h3>

<h3 /><h3>In question b, </h3>

Alternate angles are congruent

<h3 /><h3><u>y</u><u> </u><u>=</u><u> </u><u>120</u></h3>

Interior angles are supplementary

So, y + 40 + z = 180

120 + 40 + z = 180

160 + z = 180

z = 180 - 160

<h3><u>z = 20</u></h3>

Alternate angles are congruent

z = x

<h3><u>x = 20</u></h3>

.... Hope this will help....

Find slope of the graph 9x-3y=15
LekaFEV [45]
<h3><u>Explanation</u></h3>
  • Convert the equation into slope-intercept form.

y = mx + b

where m = slope and b = y-intercept.

What we have to do is to make the y-term as the subject of equation.

9x - 3y = 15 \\ 9x - 15 = 3y \\  \frac{9x - 15}{3}  = y

  • Simplify

\frac{9x}{3}  -  \frac{15}{3}  = y \\ 3x - 5 = y  \\ y = 3x - 5

From y = mx+b, the slope is 3.

<h3><u>Answer</u></h3>

\large \boxed {slope = 3}

Solve for the value of the variable: 7x+ 10 = 4x + 16<br> Enter the answer
IRISSAK [1]

Step-by-step explanation:

7x + 10 = 4x + 16

3x + 10 = 16 (subtract 4x on both sides)

3x = 6 (subtract 10 on both sides)

x = 2 (divide 3 on both sides)
