The factors of 63. Answer : 1,3,7,9<span>,21,63</span>
45 degrees! The angles of a triangle always add up to 180. The other two add up to 135. 180-135 is 45.
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
x= —3/5y+1/5z
