Answer:
D.) 8
Step-by-step explanation:
You can use the Pythagorean theorem because this is a right triangle:
a and b are the legs and c is the hypotenuse. The hypotenuse is always the longest side in a right triangle (since it is opposite the biggest angle). The two legs squared have to add up to the hypotenuse squared.
Fill in values:
Simplify exponents:
Isolate the variable. Subtract 225 from both sides:
Find the square root of both sides:
The missing leg length is 8.
Area formula of a parallelogram is
A = base x height
Given are the
Area = 60 m² and base = 10 m
Substitute the given:
60 = 10h (divide by 10 to find value of h)
(10 and 10 cancels out)
h = 6
The height of a parallelogram with a base of 10m and an area of 60m² is 6m
A = base x height
Given are the
Area = 60 m² and base = 10 m
Substitute the given:
60 = 10h (divide by 10 to find value of h)
h = 6
The height of a parallelogram with a base of 10m and an area of 60m² is 6m
Given a slope , the slope
of a line perpendicular to
is the opposite of the inverse of
In other words:
So, the slope of CD is -5/2.
