What is the area of ABC below? If necessary, round your answer to two decimal places.

irina [24]

Our goal is to find the area
area=1/2 times base times height
we know the height is 7.9 but what is the base?

use the pythagorean theorem twice
alrighty
so
remember for legs length a and b and hytponuse c in a right triangle
a²+b²=c²

we need AD and DC

so
AD²+7.9²=9.4²
AD=√25.95

DC²+7.9²=23.2²
DC=√475.83

so
AD+DC=base=(√25.95)+(√475.83)
area=1/2bh
area=1/2((√25.95)+(√475.83))(7.9)
area≈106.28518654591426812803776879893
round to 2 decimal places
area≈106.29 square units

What's absolute value |-8|

maks197457 [2]

The absolute value of a number can never be negative. That's because it represents the distance of a number from zero on a number line. The number $-8$ is $8$ digits to the left of zero on a number line. So, the absolute value of $-8$ would be $8$ .

Let me know if you have any questions regarding this problem!
