Answer:
Step-by-step explanation:
The diagram is given to you below. I could not change <C so that it was theta. So C = theta.
So C is the reference angle. Call it theta when you think of it. The diagram shows you how cos(C) must be set up.
The adjacent side is 7
The hypotenuse is 18
theta = C = cos-1(7/18) = 67.11
To the nearest degree 67.11 = 67

Answer:
it is not possible because you only know 1 side. Unless you use cos sin

Answer:
The answer to your question is:
x = 18
m∠ABD = 36°
m∠DBC = 54°
Step-by-step explanation:
m∠ABD + m∠DBC = 90°
2x + 3x = 90°
5x = 90°
x = 90/5
x = 18
m∠ABD = 2(18)
= 36°
m∠DBC = 3(18)
= 54°
Answer:
B
Step-by-step explanation:
-4x+2x>-4 is simplified to x>0. B graph correctly shows this.
Answer:
- Odd function
- Odd function
- Even function
Step-by-step explanation:
Odd function graph:
- f(–x) = –f(x) for any value of x
- symmetrical about the origin
Even function graph:
- f(x) = f(- x) for all values of x
- symmetrical about the y- axis
Answer:
AB
Step-by-step explanation:
The diameter is the line that goes from one side of the circle to the other passing through the center
The diameter is AB
It could also be named BA
