find the measure of the angle.

Best Answer

Two Angles are Supplementary if they add up to 180 degrees.

Two Angles are Complementary if they add up to 90 degrees (a Right Angle).

Let the angle be x

Supplement of the angle is (180 - x )

Complement of the angle is ( 90 - x )

So

180 - x = 2( 90 - x ) + 40

180 - x = 180 - 2x + 40

x = 40 ANSWER

supplement of 40 is 140

140 = 2 ( 90-40) + 40

The supplement of an angle x is 180° - x; the complement is 90° - x.

Here, 180° - x = 40° + 2(90° - x), or

180° - x = 40° + 180° - 2x.

Subtract 180° from both sides and add 2x to both sides, giving

x = 40°.

check: Is 180° - 40° = 40° + 180° - 2(40°)?

140° = 220° - 80°: correct. -
btw choose the below working cos it seems to be easier...

let supp be x and comp be y

x-40=2y ----(1)

90-y=180-x --(2)

from (2)

90-y=180-x

-y-90=-x

x=y+90 --------(3)

Sub (3) into (1)

y+90-40=2y

y+50=2y

y=50

ANGLE: 90-50 = 40

ANS: 40### Source(s):
