Step-by-step explanation:
If you would like to write the following in the math expression, you can do this using these steps:
a number ... n
eight less than four times a number ... 4 * n - 8
is less than 56 ... < 56
4 * n - 8 < 56
4 * n < 56 + 8
4 * n < 64 /4
n < 64 / 4
n < 16
The possible values of that number are less than 16.
Well, we know that the legs of this triangle are equal, and we know
that the area of any triangle is (1/2)(base)(height) .
Since this is a right triangle, we can set it down on one leg, and then
the other leg will be the height. Then ...
Area = (1/2) (base) (height)
= (1/2) (leg) (leg)
65 cm² = (1/2) (leg)²
Multiply each side by 2 : 130 cm² = (leg)²
Take the square root of each side: leg = √130 cm² = 11.402 cm
rounded to the nearest tenth: 11.4 cm
