Step-by-step explanation:

Since the value of that angle is 44⁰ and the angle is located on the circle, the measure of the arch x is twice the angle value.

So x=2×44⁰=88⁰

Solve the system of equations.<br><br> y equals x plus 8<br> y equals 3 x plus 2

True [87]

The solution to the system of equation is as follows:

x = 3

y = 11

<h3>How to solve the system of equation?</h3>

y = x + 8

y = 3x + 2

Using substitution method,

3x + 2 = x + 8

subtract x from both sides

3x - x + 2 = x - x + 8

2x + 2 = 8

subtract 2 from both sides

2x + 2 - 2 = 8 - 2

2x = 6

divide both sides by 2

2x / 2 = 6 / 2

x = 3

y = 3 + 8 = 11

y = 11
