Answer:
Step-by-step explanation:
We want to simplify
Recall that,
So weneed to write one base and add the exponents,
We collect LCM in the exponent to get,
We simplify to obtain,
The correct answer is A.
The length of the sides,MD, DK, and KM gives the measure of the angle m<D as c) 76°
<h3>Which method can be used to find the measure of angle m<D?</h3>In triangle ∆MDK, we have;
m = 16.4
d = 22
k = 19
Using cosine rule, we get;
d² = m² + k² - 2•m•k•cos(D)
Therefore;
2•m•k•cos(D) = m² + k² - d²
Which gives;
- m<D = 76°
The correct option is therefore;
- c) 76°
