Looking at the given triangle, we can see that it is a right angle triangle since one of the angles is 90 degrees.
For the circular water bowl to touch each side of the triangle, the center of the circular bowl would be determined by bisecting each of the angles at the vertices of the triangular table top. Therefore,
the correct option is the second one
Answer:
82.8 degrees
Step-by-step explanation:
The information given here SSS. That means side-side-side.
So we get to use law of cosines.
Let's enter are values in.
I'm going to a little simplification like multiplication and exponents.
I'm going to some more simplification like addition.
Now time for the solving part.
I'm going to subtract 164 on both sides:
I'm going to divide both sides by -160:
Simplifying left hand side fraction a little:
Now to find B since it is inside the cosine, we just have to do the inverse of cosine.
That looks like one of these:
or
Pick your favorite notation there. They are the same.
To the calculator now:
Round answer to nearest tenths:
Given:
<span>Labor
rate = $7.00 per hour
Labor time = 15 hours
Overhead rate = 110%
Retail price of parts = $38.75</span>
Total job cost = ( labor rate x labor time)(
overhead rate) + retail price
= ( $ 7 per hr x 15 hrs)( 1.10) + $ 38.75
<span>= $ 154.25 </span>
Answer:
The zeros of the function are "r=6.5, 12.5"
