Answer:
look below
Step-by-step explanation:
thing to note:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
opposite= side across angle you are using
hypotenuse= side across 90 degree angle
adjacent= remaining side
angle B
sin = 6/10
cos = 8/10
tan = 6/8
angle C
sin = 8/10
cos = 6/10
tan = 8/6
hope that helped. let me know if you have any questions:)
First add 2 2/4 and 1 3/4
= 4 1/4
Then subtract 4 1/4 from 12
= 7 3/4
The answer is B, 1/3+1/8

•] I added all of the options and got an answer of 1.35 to 1.5 and one of the choices had a answer of 0.4583 which was option B.
2y - 2 < 14
2y < 14 + 2
2y < 16
y < 16/2
y < 8
Answer:
Area = 105.133
Step-by-step explanation:
First you need to find the area of both shapes.
The area of a rectangle is length x width
A= 10*8
So the area of the rectangle is 80ft^2
The area of a circle is πr^2
Area = π4^2, but it's only a half circle so you need to divide that answer by two.
Area = π4^2 = 50.265
Then divide by 2 because it's a half circle
50.265/2= 25.132ft^2
Lastly, you need to add both areas
80+25.132= 105.133ft^2
