The cosine of an angle is equal to the adjacent side divided
by the hypotenuse. In a right triangle, the hypotenuse is the longest side. Its
value is 13. It also follows that B is the adjacent side.
To solve for B,
B = 13 cos 22.6˚ = 12
The tangent of the angle is equal to the opposite side
divided by the adjacent side. Since B is known, therefore the answer is
tan(22.6˚<span>) = a/12<span> </span></span>

To find this, you have to cut the figure into familiar shapes. In this case, you can cut it into two rectangles. When you cut it, there is a missing measurement, which is the length for the small rectangle. To find that, you subtract the other two lengths given, which is 8 and 6, and thats the length for the small rectangle. Then you do l•w for both shapes.
Answer:
54
Step-by-step explanation:
24* 2.25= 54
(.25 is 1/4 in decimal form)
40 + 2x - 30 + x + 20 = 180
3x + 30 = 180
3x = 150
x = 50
m<B = 2x - 30
m<B = 2(50) - 30
m<B = 100 - 30
m<B = 70
