The area of a right angle is 50. one of its angles is 45 degrees. find the lengths of the sides and hypotenuse of the triangle.

It's isosceles triangle (look at the picture).

The area of the this triangle:

We have

Substitute:

Use the Pythagorean theorem:

10, 10, 10√2

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
