Question

find the supplement of the complement of twice of a angle of 40°​

Answer 1

Answer:

ok this is what i say.

2angle A = 40 < 180

2A = 180 - 40

2A = 140

A = 70

angle A = 70 degrees

You're just not paying attention. You could try being deliberate and careful.

a = Measure of Angle A

Measure of Complement of Angle A ==> 90º - a

Measure of Supplement of Angle A ==> 180º - a

"Twice the complement of angle A is 40° less than the supplement of angle A."

2*(90º - a) = (180º - a) - 40º

Please develop a style of care and consistency. The expression you wrote has very little to do with the problem satatement. They should at least be related, no?

Answer 2

Answer:

4(90 - a) = 2(180 - a) - 40

360 - 4a = 360 - 2a - 40

2a = 40

a = 20

If the angle is 20, it's complement is 70 and it's supplement is 160.

Hope this helps!
