The legs of a right triangle are 6 units and 7 units. What is the length of the hypotenuse?

Ksju [112]

Answer: Square root 85 units

Step-by-step explanation:

Given: The legs of a right triangle are 6 units and 7 units.

Let h be the hypotenuse of the right triangle.

By Pythagoras theorem of right triangle, we have

$h=\sqrt{6^2+7^2}\\\\\Rightarrow\ h=\sqrt{36+49}\\\\\Rightarrow\ h=\sqrt{85}$

Hence, the length of the hypotenuse $=\sqrt{85}\text{ units.}$

Pythagoras theorem of right triangle says that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

3 Find y if the slope between ( – 7, y) and (1, 13) is 3/4

mafiozo [28]

Step-by-step explanation:

$slope \: = \frac{y2 - y1}{x2 - x1} = \frac{3}{4}$

point 1 ( -7,y)

point 2 (1,13)

$\frac{13 - y1}{1 - ( - 7)} = \frac{3}{4}$

$\frac{13 - y1}{8} = \frac{3}{4}$

$13 - y2 = \frac{8 \times 3}{4} = 6$

$y2 = 13 - 6 = 7$

y = 7
