A triangle has an area of 10.510.5 square feet. the base of the triangle is 66 feet. what is the height?

1 answer:

6 0

I'm confused... you can't have 2 decimals in a number.... anyway I'm going to help solve it as if the number was 10.5105
The formula for the area of a triangle is A = 1/2bh. So, if you were given the base and height and asked to find the area, you would multiply the base and height then divide by 2 (or multiply by 1/2, same thing). Here you have to do the opposite. Take the area, multiply it by 2, then divide it by the base.
10.5105(2) = 21.021
21.021/66 = 0.3185
h = 0.3185 ft

Hope this helped even if 0.3185 isn't the correct answer <span>because <span>10.510.5 doesn't make sense lol</span>.</span>

<h3>Answer: Approximately 6.4 units</h3>

==================================================

Explanation:

The origin is the point (0,0)

Use the distance formula to find the distance from (0, 0) to (4, -5)

Let

$(x_1,y_1) = (0,0)\\\\(x_2,y_2) = (4,-5)\\\\$

be our two points. Plug those values into the distance formula below and use a calculator to compute

$d = \sqrt{\left(x_1-x_2\right)^2+\left(y_1-y_2\right)^2}\\\\d = \sqrt{\left(0-4\right)^2+\left(0-(-5)\right)^2}\\\\d = \sqrt{\left(0-4\right)^2+\left(0+5\right)^2}\\\\d = \sqrt{\left(-4\right)^2+\left(5\right)^2}\\\\d = \sqrt{16+25}\\\\d = \sqrt{41} \ \text{ exact distance}\\\\d \approx 6.40312 \ \text{ approximate distance}\\\\d \approx 6.4\\\\$
