By applying Pythagorean's theorem, the missing side of this right-angled triangle is: A. 7√3 inches.
<h3>How to find the missing side?</h3>
By critically observing the triangle shown in the image attached below, we can logically deduce that it is a right-angled triangle. Thus, we would find the missing side by applying Pythagorean's theorem:
z² = x² + y²
Also, the sides of this right-angled triangle are:
- Opposite side = x inches.
- Adjacent side = 7 inches.
Substituting the given parameters into the formula, we have;
14² = x² + 7²
196 = x² + 49
x² = 196 - 49
x² = 147
x = √147
x = √49 × √3
x = 7√3 inches.

Answer: D. 27.5 square inches /inches?/ I think, correct is units
As a fraction it is 16/9 and for a decimal it is 1.7777 repeating
Answer:
132 cm^2
Step-by-step explanation:
Find all areas and add together.
A = L x W
tA = (L x W)/2
30 + 30 + 48 + 12 + 12 = 132
