∠1 and ∠2 are complementary. ∠1=x°∠2=(3x+30)° select from the drop down menu to correctly answer the question. what is the value of x? . a.15 b.25 c.30 d.40 e.55

A =15

Step-by-step explanation:

Complementary angles add to 90 degrees

<1 + <2 =90

x + 3x+30 =90

Combine like terms

4x+30 =90

Subtract 30 from each side

4x+30-30 = 90-30

4x= 60

Divide by 4

4x/4 = 60/4

x = 15

Option A

The value of x is

Step-by-step explanation:

we know that

If two angles are complementary, then its sum is equal to

In this problem we have that

------> equation A

we have

Substitute the values of m<1 and m<2 in the equation A and solve for x
