Answer:

Step-by-step explanation:

Let the measurement of the smaller angle = x

Larger angle = 4x + 10

x + (4x + 10) = 90    {complementry}

5x  + 10  = 90

        5x = 90 -10

         5x = 80

            x = 80/5

            x = 16

Smaller angle = 16

Larger angle = 4*16 + 10 = 64+10 = 74

Answer:

a=16

b=74

Step-by-step explanation:

If two angles are complementary to each other, then their sum is 90 degrees.

So we have: a+b=90.

Let's say b is the larger of the two.

We have that b is 10 more than 4 times the measure of a.

An equation this is: b=10+4a.

So I'm going to plug second equation into first equation:

a+b=90 with b=10+4a:

a+(10+4a)=90

Combine like terms:

5a+10=90

Subtract 10 on both sides:

5a=80

Divide both sides by 5:

a=\frac{80}{5}

Simplify:

a=16

Now to find b:

b=10+4a with a=16:

b=10+4(16)

b=10+64

b=74
