Hello!
Question 1
In a 30-60-90 triangle the hypotenuse is 2x the height is
and the base is x
Find x
11 = 2x
Divide both sides by 2
5.5 = x
Put in x into the other equations
x = 5.5
2x = 11
11 + 5.5 + 9.5 = 26
We put the equations into a calculator and see which one is close to 26
The answer is B) 33/2 + 11/2 * the square root of 3
------------------------------------------------------------------------------------------------------
Question 2
For this one we can put the choices into a calculator and see what comes up close to 15
tan(86.19°) = 15.01
the answer is D) 86.19°
Hope this helps!
