Question

Two angles are supplementary.If one of them is 30° less than five times the other. find the angles.​

Answer 1

Answer:

Step-by-step explanation:

Name the quadrilaterals which have both line and rotational symmetry of order more than 1.

Answer 2

Answer:

Let the angles be x and y

x + y = 180…..(i)

y = 4x + 30……(ii)

Hence, x + 4x + 30 = 180 [substituting (ii) in (i)]

Hence, 5x + 30 = 180

Hence, 5x + 30 - 30 = 180 - 30

Hence, 5x = 150

Hence, 5x/5 = 150/5

Hence, x = 30

Substitute in (ii)

y = 4*30 + 30 = 5*30 = 150

The angles are 30 and 150 degrees.
