Answer:
acute and isosceles
Step-by-step explanation:
acute because all angles less than 90
isosceles because 2 sides are equal length
The y's value is given in the first equation.

. Now to solve, we will, plug it's value in the second equation.

Now we have x's value, we will plug it's value in the first equation.(We can plug it in the second one too, but plugging it the first one will make it easier.)
Answer:
Height of the building = 50.8 ft
Step-by-step explanation:
A person and a building are casting the shadows at the same time of the day.
Triangles formed by the person and his shadow and the building and its shadow will be similar.
Therefore, corresponding sides of the similar triangles will be proportional.

x = 
x = 50.75
x ≈ 50.8 ft
