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
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.
