x = 11.2 this is rounded to the nearest tenth :)
Answer:
b. 0.850887688656
Step-by-step explanation:
Unless the argument of the sine function is specified in degrees or some other angle unit (revolutions, grads, minutes, seconds), it must be assumed to be radians. Here, the argument 310 is not shown as 310°, so we must assume it is 310 radians.
sin(310) ≈ 0.850887688656

<em>Additional comment</em>
sin(310°) ≈ –0.766044443119
A radian is dimensionless, indistinguishable from a pure number.
Answer: 
Step-by-step explanation:
Simply divide by c to isolate x.
Answer:
z+42+42=180
Step-by-step explanation:
Since it is an isosceles triangle, the two base angles are the same and remember all the angles add to 180. So use this equation:
z+42+42=180
If you need to find z, it is 96.
Check: 96+42+42=180
