What are you trying to find
Answer:
110.23
Step-by-step explanation:
I just substituted 4 for x in the equation
The answer is 108°
A regular pentagon has all its five sides equal and all five angles are also equal. Hence, the measure of each interior angle of a regular pentagon is given by the below formula. Measure of each interior angle = [(n – 2) × 180°]/n = 540°/5 = 108°.
Example 1: The angle is 42 deg and the length of the hypotenuse is 25. The side of length x is opposite the 42 deg angle.
opposite side
Thus, sin 42 deg = -------------------- => 25 sin 42 deg = x = opp side
25
25(0.669) = 16.7 units (answer)
