Answer:
48 degrees
Step-by-step explanation:
<u>1) Solve for x</u>
Complementary angles add up to 90 degrees. Therefore, m<A + m<B is equal to 90:
Open up the parentheses
Subtract 20 from both sides
Divide both sides by 5
Therefore, x is equal to 14.
<u>2) Determine angle A</u>
Substitute x with 14
Therefore, the measure of angle A in degrees is 48 degrees.

Answer:
Step-by-step explanation:
1) if to re-write the given equation into slope-interception form, then:
the slope of the given line is 5/2;
2) according to the rule of perpendicular, the required slope should be:
s*(5/2)=-1;
3) if to solve this equation (s*5/2=-1), then s=-2/5 or -0.4.
