Given the rectangle at the right, as labeled. To the nearest degree, find the measure of ∠BCA. HELP PLEASE STEP BY STEP

I got u

Step-by-step explanation:

The Pythagorean Theorem,

a

2

+

b

2

=

c

2

,

is used to find the length of any side of a right triangle.

In a right triangle, one of the angles has a value of 90 degrees.

The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle.

If the length of the hypotenuse is labeled

c

, and the lengths of the other sides are labeled

a

and

b

, the Pythagorean Theorem states that

a

2

+

b

2

=

c

2

.

Key Terms

legs: The sides adjacent to the right angle in a right triangle.

right triangle: A

-sided shape where one angle has a value of

90

degrees

hypotenuse: The side opposite the right angle of a triangle, and the longest side of a right triangle.

Pythagorean theorem: The sum of the areas of the two squares on the legs (

a

and

b

) is equal to the area of the square on the hypotenuse (

c

). The formula is
