Sin of an angle=opposite side/hypotenuese
cos of an angle=adjacent side/ hypotenuese
tan of an angle=opposite side / adjacent side
11. sine M=7/25 12. do the same but using the number of this triangle
cos M=24/25
tan M=7/24
14. They give you the angle 35 degrees. So that will be what you start with. Look at the lengths of the sides given. Where are they located in respect to the angle 35. 20 is the hypoteneuse, and x is opposite of 35. So the equation that uses hypoteneuse and opposite is sin.
sin 35=35/x, punch in sin 35 into the calculator. then you would get .57=35/x. The cross multiply .57x=35=61.40.
Now you can repeat for the rest of the problems. I hope this is helpful.
Double of 50 is 100, so 28*100=2800, now half of the answer is 2800/2=1400
Hope it helped
We need to find the value of the hypotenuse in order to solve this problem.
12^2+4^2=H^2
Therefore:
H=√(144+16)
H=4√10
Now:
sin(G)=O/H=4/(4√10)
=1/(√10)
=(√10)/10
Answer:
75 in²
Step-by-step explanation:
(see attached for reference)
recall that the formula for area of a circle is given by
Area = π r²
where
π = given to be 3
r = radius given as 5 in
simply substituting the values into the equation:
Area = π r²
= 3 x 5²
= 3 x 25
= 75 in²
