5.5 feet is the distance of Irene's eyes from the ground.
4 feet is the distance of Irene from the mirror
From this, we can draw a right triangle and then use the Pythagorean theorem to solve for the height of the oak tree. Also, we have an option to use ratio and proportion between two similar triangles.
Answer:
It's acute triangle
Step-by-step explanation:
c^2 = 19^2 = 361
a^2 + b^2 = 15^2 + 13^2 = 225 + 169 = 394
c^ < a^2 + b^2 > . It's acute triangle
