The angle is 20 degrees
40 degres
The supplement of A is 180 - A The complement of A is 90 - A So, 180 - A = 2*(90 - A) + 20 or 180 - A = 180 - 2A + 20 So A = 20 degrees
The complement is 60 degrees.
Suppose the supplement of the angle is x degrees. Then the angle is 180 - x degrees. Therefore the complement of the angle is 90 - (180 - x) degrees = x - 90 degrees. So 5*(x - 90) - 2*x = 40 Solve the above equation for x.
The angle is 60°. Its supplement is 120°.
60 degrees.
180-x= 2(90+x) - 60 180-x=180+2x - 60 -x=-60 x=60 Are you in my honors geometry class? The algebra is wrong. the third line should read -3x=-60 x=20 therefore the complement is 70o This agrees with the answer in the back of the book.
Supplementary angles add up to 180° Complementary angles add up to 90° Let the angle be θ; then form an equation from the known facts: 1) Supplement: 180° - θ 2) Complement: 90° - θ → twice complement is (90° - θ) × 2 → increased by 65° is (90° - θ) × 2 + 65° These two are equal, thus: 180° - θ = (90° - θ) × 2 + 65° → 180° - θ = 180° - 2θ + 65° → θ = 65° The angle is 65°.
A supplemental angle "completes" a given angle to make it a straight angle (180 degrees). The supplement of 90 is 90. The supplement of 100 is 80. As long as the two angles add up to 180 they supplement each other. So, you have some angle, x and its supplement, 180-x. The supplement is twice as big as the angle. 180-x = 2*x Solve for x and you're done!
two-thirds of an angle is 30degree more than its supplemant. find the angle
116 degrees
