Area of a triangle = base x height / 2
64 = base x height / 2
(multiply 2 on both sides)
128 = base x height
then if base= 16 and height = 8 then 16 x 8 = 128
thus the base is 16 which is twice the height:8
This answer would be 21 because you’d just do 15 increased by 40% which gave me 21
Im sorry but im not sure what your asking
We have been given that ∠Q is an acute angle such that
. We are asked to find the measure of angle Q to nearest tenth of a degree.
We will use arctan to solve for measure of angle Q as:

Now we will use calculator to solve for Q as:

Upon rounding to nearest tenth of degree, we will get:

Therefore, measure of angle Q is approximately 2.3 degrees.
