Answer:

30°

Step-by-step explanation:

A triangle always adds up to 180° so since one side of the triangle is already 90°, that means the other two sides add up to be 90° as well.

x + 2x = 90 \\ 3x = 90 \\  \frac{3x}{3}  =  \frac{90}{3}  \\ x = 30

It'll be 4^2+ 3^2 then the answer you get you take the square root of it which will give you the hypotenuse.
Your answer would be 5 because square root of 25 is 5
If u want the formula it's a^2+b^=c^2
C is the hypotenuse and a and b is the lengths
