tino4ka555 [31]

Answer:

49π

Step-by-step explanation:

area of circle = πr^2

<em>Handy Tip: cherry pies delicious; apple pies are(R) too(2)! so C = πd and A = πr^2</em>

Im in 10th grade geometry and need help
gulaghasi [49]

Answer: x = 15 ; y = 15√2

Concept:

The given triangle in the question is a 45°-45°-90° triangle.

It is considered to be a special triangle where the ratio of side lengths is 1:1:√2, meaning that the legs that correspond with 45° are 1, while the hypotenuse which corresponds with 90° is √2.

Please refer to the attachment below for a graphical explanation.

Given:

A 45°-45°-90° triangle

Leg₁: 15

Solve:

Knowing that the ratio of the triangle is 1 : 1 : √2

<u>Find the value of x</u>

x leg correspond with 45° angle

Leg₁ correspond with 45° angle

Leg₁ = 15

∵ The given ratio is 1 : 1 for 45° angle

\boxed{x=15}

<u>Find the value of y</u>

y hypotenuse correspond with 90° angle

Leg₁ correspond with 45° angle

Leg₁ = 15

∵ The given ratio is 1 : √2 for 45° : 90° angle

\boxed{y=15\sqrt{2} }

Hope this helps!! :)
