What is the value of x?

45°

Step-by-step explanation:

SRV is a straight line with a angle of 180° therefore the sum of 3x and x is 180° as well

X + 3X = 180°

4X = 180°

X = 45°

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

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
