Angles y and c are complementary angles. The measure of y is (5x+2),and the measure of c is (x+10),what is the value of y and c help?

y & c are complementary
=>
5x+2*+x+10*=90*
=>
6x=90*-12*
=>
x=13*
=>
y=5(13*)+2*=67*
c=13*+10*=23*

Complementary means that the angles add up to 90 degrees.
6x + 12 = 90
x = 13
c is (x + 10) = 23°
y is (5x + 2) = 67°

Angles y and c are complementary angles.
The measure of y is (5x + 2), and
the measure of c is (x + 10).
6x + 12 = 90°, x = 13
The value of y = 67° and
the value of c = 23°

Remember the definition of complementary (and supplementary) angles.
Complementary angles (think 'C' = corner = 90°) add up to 90°
Supplementary angles (think 'S' = straight = 180°) add up to 180°
So first add up the angles and solve for x:
5x+2 + x+10 = 90
6x + 12 = 90
6x = 90 - 12
6x = 78
x = 78/6
x = 13
Now figure out the two angles:
∠y = 5x + 2 --> 5(13) + 2 = 67°
∠c = x + 10 --> 13 + 10 = 23°
Double-check that those two angles do indeed add up to 90°.
