$40 + $7.50x = 62.50 so what you do is take 62.50 - 40 = 22.50 and divide 22.50 by 7.50 which is 3 so 3 hours
<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°
Subtract the 18 from the 78 then multiply both sides by -1, then divide by 5.
1.2*3= 3.6
28-19=9
