Angels 1 and 2 are complementary the measure of angle 2 is 2 times the measure of Angel 1 write and solve an equation to find th
creativ13 [48]

Two complementary angles sum is 90 degrees.

Angle 1 = x

Angle 2 = 2x ( two times angle 1)

Equation: x + 2x = 90

Solve:

Combine like terms:

3x = 90

Divide both sides by 3:

X = 90/3

X = 30

Angle 1= 30

Angle 2 = 60

Evgen [1.6K]

Answer:

Total walk she did around the pool every morning = 141.3

Step-by-step explanation:

Given - Kriti has a circular swimming pool in her house. The radius of the swimming  pool is 22.5 cm. She walks one round every morning before diving in the pool.

To find - How far does she walk around the pool every morning?

Proof -

Given that, the swimming pool is circular in shape.

So,

1 round of circle = Circumference of circle.

As we know that,

Circumference = 2\pi r

                         = 2*\pi *22.5

                         = 141.3

∴ we get

Total walk she did around the pool every morning = 141.3

Please help me. I can't figure this out. I've been doing math for 5 hours and that's not an exaggeration.
svetlana [45]

Well you have to do PEMDAS

So we have an exponent so that will turn into a positive X

X+4x=10

So now we combine our X's together to get 5X=10

Now we divide both sides by X which gives us 2

Sorry read the problem wrong
