If x and y are the two angles, then
x + y = 90
and x - y = 18
Adding the two equations together gives 2x = 108 so that x = 54
and then y = x - 18 = 36

false but You can find the measure of an exterior angle by using supplementary angles.
Two complementary angles add up to 90°. So we have, y + (y - 16) = 90 2y - 16 = 90 add 16 to both sides; 2y = 106 divide by 2 to both sides; y = 53 y - 16 = 53 - 16 = 37 Thus the smallest angle is 37°.
Yes
it equals to 3420 degrees
2x-10+3x-10=90 5x-20=90 5x=110 x=22
The methods are subtraction. -- Subtract an angle from 90° to find its complementary angle. -- Subtract an angle from 180° to find its supplementary angle.
23 degrees and 67 degrees
Complementary angles total 90 degrees so smaller is 90/5 ie 18 and larger 72.
Difference between two complementary angle is 60 degree find its angle
If the angles are A and B, then A - B = 18 Also, comp angles => A + B = 90 So A = 54 deg, B = 36 deg
find the sum of the measures of the interior angles of 13-gon.
90-20= 50 so50 is the complementary angle of 20
If there were not that difference of 3o, the angles would be 60 and 30. Because of the difference the angles must be 61o and 29o.
112.5 degrees
Complementary angles are found by subtracting a random angle from 90 degrees for complementary always and 180 for supplementary always
