In ΔDEF, the measure of ∠F=90°, EF = 2.3 feet, and FD = 2.9 feet. Find the measure of ∠D to the nearest tenth of a degree.

Step-by-step explanation:

From the question we are told that:

Angle of F

Length of

Length of

Generally the equation for Angle D is mathematically given by

Since .The triangle  is a right angle Triangle

Therefore

actually what is a question i don't understand
