Step-by-step explanation:
Answer:
B. 59°
Step-by-step explanation:
<AOC=77°
<BOC=?
THEREFORE,
<AOC=<BOC+<AOB
77° =7x+17+3x
77°-17=7x+3x
60=10x
x=60/10
x=6°
Now,
<BOC=7x+17
=7*6+17
=42+17
=59
Answer:
a number plus 5 equals 12.
Step-by-step explanation:
The square root parent function is:
B. F(x)= √x
Answer:
The solutions of the equation are -41.8° , 0.0° , 41.8°
Step-by-step explanation:
∵ 3 sin²Ф - 2 sinФ = 0 is a quadratic function
∵ The domain of the function is -90° ≤ Ф ≤ 90°
- Lets take sinФ as a common factor
∴ sinФ (3 sinФ - 2) = 0
- Two terms multiplied by each other = 0
∴ One of them must be equal zero
∴ sinФ = 0 or 3 sinФ - 2 = 0
- If sinФ = 0 ⇒ Ф = 0.0°
- If 3 sinФ - 2 = 0 ⇒ 3 sinФ = 2 ⇒ sin Ф = 2/3
∵ sinФ 2/3
∴ Ф = 41.8° ⇒ Ф ≤ 90° (in first quadrant)
∵ -90° ≤ Ф ≤ 90°
∴ Ф = -41.8° ⇒ Ф ≥ -90° (in fourth quadrant)
∴ The solutions of the equation are -41.8° , 0.0° , 41.8°
