Answer:
2(5) + 2x
Step-by-step explanation:
The equation to find perimeter is <em>P = 2L + 2W ( P = L + L + W + W )</em>
Since this question is asking for an expression to solve for the perimeter of this particular rectangle, I would say 2(5) + 2x. A simpler expression could be 10 + 2x.
Answer:
5x - 30
Step-by-step explanation:
I used the distributive property and I think I got it.
<u>Given</u>:
Line m is parallel to line n.
The measure of ∠1 is (4x + 15)°
The measure of ∠2 is (9x + 35)°
We need to determine the measure of ∠1
<u>Value of x:</u>
From the figure, it is obvious that ∠1 and ∠2 are linear pairs.
Thus, we have;

Substituting the measures of ∠1 and ∠2, we get;




Thus, the value of x is 10.
<u>Measure of ∠1:</u>
The measure of ∠1 can be determined by substituting x = 10 in the measure of ∠1
Thus, we have;



Thus, the measure of ∠1 is 55°
