What is the area, in square millimeters, of a right triangle with a hypotenuse of 68 millimeters and a leg of 60 millimeters?

Paladinen [302]

First, we have to solve the sides of the right triangle by using the Pythagorean theorem: a² + b² = c² where c is the length of the hypotenuse. Then, we can use the legs as length and height of the triangle and find the area by 1/2(base x height).

x² + 60² = 68²
x² + 3600 = 4624
x² = 1024
x = √1024
x = 32 = length of the other side

A = (1/2)(32) (60) = 960 mm²

What is the simplified form of the equation fraction 3 over 5 n minus fraction 4 over 5 equals fraction 1 over 5 n?

Yuki888 [10]

n = fraction 5 over 3

Explanation;
 $\frac{3}{5}n- \frac{4}{5}= \frac{1}{5} n$
Eliminate the demominator by multiplying each term by 5.
3n-4=1
3n=5
n= $\frac{5}{3}$
