<h3>Answer:</h3><h3>See below</h3>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
- law of sine
- law of cosine
- PEMDAS
<h3>let's solve:</h3>
there are 3 ways to solve SAS triangle
- use The Law of Cosines to calculate the unknown side,
- then use The Law of Sines to find the smaller of the other two angles
- and then use the three angles add to 180° to find the last angle.
first figure out
to do so we will use the formula of law of cosine of C angle
substitute the given values of a,b and
simplify squares:
simplify addition:
square root both sides
simplify:
therefore
use law of sine to figure out angle A
therefore
(use calculater to simplify it)
therefore
Answer: 12,000 lbs is equal to 6 tons
D.perpendicular as perpendicular lines create 90 degree angle.
Answer:
968π ≈ 3041 . . . cubic units
Step-by-step explanation:
The usual formula for the volume of a cylinder is ...
V = πr²h
For your given dimensions, the volume is found by putting the values into the formula and doing the arithmetic.
V = π(11²)(8) = 968π . . . . cubic units
V ≈ 3041 cubic units
1) not function because 6 number repeat in domain
2) Function
For 3 and 4 I guess it's
3) Function
4)not function
If any number repeat twice in the domain that will be not a function
