Answer:
the ratio is 12:7 but im not 100% sure
Divide across and just bring down the numbers
This is the concept of trigonometry, the value of x will be calculated as follows;
sin theta=[opposite]/[hypotenuse]
theta=x
opposite=16 units
hypotenuse=21 units
thus;
sin x=16/21
hence;
x=arcsin(16/21)
x=49.63
x=50 (to the nearest degrees)
Answer:
-2
Step-by-step explanation:
We can set it equal to zero
2x+4 = 0
2x =-4
x = -2
