The answer is D. Think of the Pythagorean Theorem which states that a^2 + b^2 = c^2. The Pythagorean Identities used in trigonometry are the angle version which can be used to simplify expressions.
1 can go into anything so that is the mystery number sorry if not right first time on here
1 because it is reveresed
Answer:
60
Step-by-step explanation:
Total degree of triangle interior angles is 180
So x+2x+3x=180
6x=180
x=30
Measurement of angle C is 2x which is 60 degree
Answer:
The length and width of the prism are 20 metres and 5 metres respectively
Step-by-step explanation: given that the length of a rectangular prism is four times its width. That is
Length L = 4 width W
L = 4W
the volume of the prism is 380 cubic meters
V = L × W × H
380 = 4W × W × H
380 = 4W^2H
W^2H = 380/4
W^2 H = 95
The only way to get a perfect square number is to make H = 3.8
3.8W^2 = 95
W^2 = 95/3.8
W^2 = 25
W = 5
But L = 4W
L = 4 × 5 = 20
The length and width of the prism are therefore 20 metres and 5 metres respectively
