Answer:
sqrt(217)/19
Step-by-step explanation:
sin²(theta) = 1 - cos²(theta)
= 1 - (-12/19)²
sin²(theta) = 217/361
sine is positive in quadrant 2
Take the positive root
sin(theta) = sqrt(217)/19
Answer:
use 3
Step-by-step explanation:
The inequality is 4 ≥ x/2.1, and the answer is 8.4 ≥ x (or x ≤ 8.4).
To solve this, we multiply both sides by 2.1:
4*2.1 ≥ x
8.4 ≥ x.
Well, if you look into it, inspect element thsi, really. I believe it is either A, Or C. But I am more strong with A.
Answer:
Step-by-step explanation:
Multiply: -4 and 5 which then equals X
Add Exponents: and then which finally equals to the answer,
