Given:
Base length of triangle = 10 units
Height of triangle = 
units
Length of hypotenuse of triangle = 12 units
To find:
Exact value of Cos A
Steps:
The cosine of any angle is equal to the length of the adjacent side by the length of the hypotenuse side.
So,
Cos A = 
Cos A = 
Cos A = 0.833
Therefore, the exact value of cos A is 0.833.

Answer:
D.
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals. That means that their product is -1.
In option D, since the slopes are 1 and -1, their product is -1, and the lines are perpendicular.
Answer: D.
Answer:
Step-by-step explanation:
Z = (x-µ)/(s/√n)=(98.5-98.2)/(0.62/√19) = 2.11
left tail p-value = 0.9826
so 98.26% are lower.
We know that:
C=πd Were π(pi)=3,14... and d=diameter
We know that the radious is 2d, so we aply this to the formula and we get that:
C=2πr
