I believe it is 64 because 8 times 8 is 64
The correct answer is C. this is because the Cosine of (22 + 2) = 0.91 and the Sine of (3 x 22) = 0.91
Answer:
75°
Step-by-step explanation:
firstly, use the pythagoras theorem
Square root(8²-2²) = 7.75
Then, use sine
sine A= 7.75/8
Sine A=0.9688
A= (sine power of -1) x (0.9688)
A=75.63
*I'll be keeping the solutions in exact form*
So firstly, square root both sides. This will split the equation into two:

Next, add 1 on each side: 
Next, divide 3 on both sides, and your answers will be 
451
x36
multiply
the answer=16236
