Question

find the measure of an angle which is 30 degree less than its complement
​

Answer 1

Answer:

30 DEGREES

Step-by-step explanation:

Let one of the angles be x and the other x-30.

Sum of the complements is 90 degree.

Given,

x+x-30 = 90

2x = 90+30 = 120

Therefore, x= 120/2 = 60

So the angle which is 30 degree less than its complement is 60-30= 30 degrees.

Answer 2

Step-by-step explanation:

let the angle be x

so the other angle would be x-30

complementary angles means that the sum of the angles is equal to 90degrees

so :

x+x-30=90

2x-30=90

2x=90+30

2x=120

x=120/2

x=60

if x is 60 then the other angle would be x-30=60-30=30

so the answer is 30
