Answer:
87 feet
Step-by-step explanation:
We have an angle that's 44 degrees and we know that Susan is 90 feet from the base of the tree. We need to know the height of the tree, which is the value opposite from the angle we know.
Use tangent to find height.
tan (44) = x / 90 then multiply both sides by 90
x = tan (44) * 90 evaluate tan(44) and substitute into the equation
x = 86.911
round to nearest whole foot: 87 feet
