Please help with this. This is a major grade

68°

Step-by-step explanation:

Refer to the picture above. Therefore,

angle NKQ + 90 + 90 + 112 = 360

angle NKQ = 68°

i think 5 miles per hour

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
