11 is D
Step-by-step explanation:
Answer:
y = √-1040/7
Step-by-step explanation:
The equation of a unit circle is expressed as;
x²+y² = 1
Given the coordinate of P = (-33/7, y)
Substitute the coordinate into the give expression and find y;
(-33/7)²+y² = 1
Expand
y² = 1-(-33/7)²
According to difference of two square
y² = (1+(-33/7))1-(-33/7))
y² = (1-33/7)(1+33/7)
y² = -26/7(40/7)
y² = -1040/49
y= √-1040/49
y = √-1040/√49
y = √-1040/7
Hence the value of y is y = √-1040/7
Answer:
40
Step-by-step explanation:
Answer:
D) 73.5º
Step-by-step explanation:
Law of sines
sinQ/15 =sin50.1/12
multiply both sides by 15
sinQ = sin50.1/12 * 15
sinQ = 0.958956439769124
Q = arcsin0.958956439769124
Q = 73.5º
