Answer:
Step-by-step explanation:
In order to solve this quadratic, we have many methods. We can factor, complete the square, or use the quadratic formula. I'm going to factor since it's the easiest method.
To factor, find two numbers that when multiplied equal a(c) and when added equal b.
a=1, b=-4, and c=-5.
So we want two numbers that when multiplied equals 1(-5)=-5 and when added equals -4.
-5 and 1 are the possible numbers. Therefore:
√52 square root of 52, 6*6=36 -4*-4=16 add them together and then square root that number
The area of any triangle is
(1/2) · (base · height) .
As soon as you know the base and the height, simply
write them into that formula to calculate the area.
Supplementary angles.
Supplementary angles are two angles that add up to 180 degrees.
