It's letter c
multiply the coefficient then just add the degrees of each letter
The answer is c because k and m are the same so l and n are also the same
Answer:
The answer is
<h2>12.3 cm</h2>
Step-by-step explanation:
Since the triangle is a right angled triangle we can use trigonometric ratios to find y
To find y we use cosine
cos∅ = adjacent / hypotenuse
From the question
y is the adjacent
The hypotenuse is 15
So we have

We have the final answer as
<h3>12.3 cm to the nearest tenth</h3>
