Step-by-step explanation:
Answer:
56.27 in
Step-by-step explanation:
You can determine the length of the missing side IH by using sine law.
In the form of a/sinA = b/sinB = c/sinC, you can substitute an angle and its corresponding side, which in this case is angle I and side i, and do so with the other angle, which is angle X and side x.
<u> 74 </u> = <u> IH </u>
sin97 sin49
after this, multiply both sides by sin49 to isolate side IH -
(sin49) x <u> 74 </u> = IH
sin97
now plug all the numbers into a calculator and you will get the answer, 56.26792; when rounded, it should be 56.27 in.
C=2pir
area=pir^2
given
c=25.12
25.12=2pir
pi=3.14
25.12=2(3.14)r
25.12=6.28r
divide both sides by 6.25
4=r
sub into other
area=pir^2
area=pi4^2
area=16pi
area=16(3.14)
area=50.24
the area is 50.24 square cm
When you have

you can solve the equation by multiplying both sides by 1/4. Then simplify.
