Answer:

x = 18.

Step-by-step explanation:

The 2 amgles are adjacent so add up to 180 degrees so we have:

x^2 - 11x + 3x = 180

x^2 - 8x - 180 = 0

(x -18)(x + 10) = 0

x = -10, 18.

x = -10 cannot be correct because that would make the 3x angle = -30.

10-d = -34-5d solve this equation

algol13

<h3><u>Explanation</u></h3>

Given the equation.

$10 - d = - 34 - 5d$

Solve the equation for d-term.

Because we cannot subtract or add up constants and variables, we simply move the same variable term to the same side and constant term to the same constant side.

$10 + 34 = - 5d + d \\ 44 = - 4d \\ \frac{44}{ - 4} = d \\ - 11 = d$

Answer Check

Substitute d = -11 in the equation.

$10 - ( - 11) = - 34 - 5( - 11) \\ 10 + 11 = - 34 + 55 \\ 21 = 21$

The equation is true for d = -11.

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

<u> $\large \boxed{d = - 11}$ </u>
