Find the value of the variable. Leave your answer in simplest radical form. a) 2√10

b) 2√5

c) √5

d) √10

i'll give brainliest !! please

Step-by-step explanation:

This is a 45-45-90 triangle whose leg to hypotenuse ratio is 1 /

so I set up a proportion of 1 / = x / 2

cross-multiply to get x = 2

x = 2 / and multiply numerator and denominator by , this is called rationalizing the denominator

i think it is c, not positive though

step-by-step explanation:

find the magnitude of the trig term
