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
wikianswers isn't for your math homework. Sorry kid.
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.
Complementary angles add up to 90*, so a 60* angle's complement is 30*.
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.
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.
90-20= 50 so50 is the complementary angle of 20
112.5 degrees
Complementary angles are found by subtracting a random angle from 90 degrees for complementary always and 180 for supplementary always
By definition, they must sum to 90 degrees.
