Answer:
X=4
Step-by-step explanation:
i Think
Angle 4 and 1 are the same. Since angle 4 is 49 degrees so is angle 1. So just plug 49 into the equation for angle 1 and that would look like 49=3x-18. Then solve. Check your work with other equations given.
Answer:
5x+15
Step-by-step explanation:
area=Length X Width
area= 5 X x+3
area=5(x+3)
area=5x+15

Answer: A. The period is 2pi/b</h3>
Explanation:
The value of 'a' out front in y = a sin(bx) determines the amplitude.
The b term helps us compute the period, which is 2pi/b for sine, cosine, secant, and cosecant functions.
For example, y = 2sin(3x) has an amplitude of 2 and period of 2pi/3
For tangent and cotangent functions, the period would be pi/b.
