Question

Help time Find the value of x. 

Answer 1

Answer:

The answer would be 3 times square root of 2 divided by 2. If you use the formula and work backwards, by plugging in each one of these and solving for 90 degrees, you would see that none of them work except this one.

Answer 2

Answer:

x = 3√2 / 2

Step-by-step explanation:

45 45 90 right triangle

Ratio of leg : hypo = x : x√2

Given hypo = 3 so leg = 3√2 / 2

Double check:

leg = 3√2 / 2

hypo =  leg √2

= 3√2 / 2 * (√2)

= 3 * 2 / 2

= 3
