By Pythagoras theorem, as
(hypotenuse)^2=( one side)^2 + (other side)^2
hope it helps u
You have not provided the choices, therefore, I cannot provide you with a specific solution. However, I will explain this problem for you to understand an apply on the choices you have.
Now, the perimeter of the rectangle is the summation of lengths of its four sides.
We have:
length = 12 ft
width = 9 ft
Therefore:
perimeter = 12 + 9 + 12 + 9 = 42 ft
Or: perimeter = 2(12+9) = 2*21 = 42 ft
Or: perimeter = 2*12 + 2*9 = 24 + 18 = 42 ft
Any expression that does not lead to the above result would be wrong
Hope this helps :)
Incomplete Question the complete Question with figure is below.
Answer:
Therefore the length of line Segment BC is 20.5 in.
Step-by-step explanation:
Given:
In Right Angle Triangle ABC
∠C = 90°
∠B = 35°
BC = a
AB = hypotenuse = 25
To Find:
BC = ?
Solution:
In Right Angle Triangle ABC , Using Cosine Identity we get
Substituting we get
Therefore the length of line Segment BC is 20.5 in.
The last one is incorrect. The correct answer is division. They divided 9 on both sides.
