Answer:

x=13°

Step-by-step explanation:

It is given that triangles ABC and EDC are similar, therefore angles ABC and EDC have the same measurement. Using this information, we can set up an equation.

(8x+16)=120

We can remove the parentheses, as they are unnecessary.

8x+16=120

We can now solve the equation for x. The first step is subtracting 16 from both sides.

8x=104

We can now divide both sides by 8, to isolate x. 104/8=13.

x=13

Lets not forget to add the degree symbol, as the problems is dealing with degrees.

x=13°

saw5 [17]

Answer:

Given the statement:

9 less than the sum of x and 5

"Sum of x and 5" means x+5

"\text{less than}" means subtract

then;

the statement 9 less than the sum of x and 5 becomes;

⇒(x+5) - 9

⇒x+5-9 = x-4

Therefore, the expression for the given statement is (x+5) - 9
