Answer:
x=45
Step-by-step explanation:
An entire triangle is 180 degrees and you already know that one angle is 90 degrees. 180 - 90 is 90. Now you have the equation 2x=90.
You then divide each side by 2 to get the x by itself which leaves you with x=45.
Expressions can be read as how many times you're multiplying a number by itself.
(1/2)^4 can be rewriten as (1/2)*(1/2)*(1/2)*(1/2), which simplifies to 1/16
