Remember that tif the legs of a right tirsnalge are a and b and they hypoonuse is c then
a²+b²=c²
so
we also know that the area of a triangle is 1/2bh
we are given that area=60 and base=8
so
60=1/2 times 8 times height
60=4 times height
divide both sides by 4
15=height
so the legs are 15 and 8
a=15
b=8
15²+8²=c²
225+64=c²
289=c²
sqrt both sides
17=c
the hypoonuse is 17ft
For this case we must factor the following expression:
We must find two numbers that, when multiplied, result in -4, and when added, result in -3.
These numbers are: -4 and +1
So:
Answer:
Option A
