If the original angle is x degrees then its supplement is 180 - x degrees.
we have the equation:-
180 - x = 3x + 20
160 = 4x
x = 40
The original angle is 40 degrees and its supplement is 140 degrees
Answer:
A = 64 units²
Step-by-step explanation:
A = 1/2bh
Step 1: Define
A = ?
b = 16 units
h = 8 units
Step 2: Substitute and Evaluate
A = 1/2(16 units)(8 units)
A = (8 units)(8 units)
A = 64 units²
Answer: To find the volume of a cube, use the formula V=lwh, or Volume equals length times width times height.
The value of X is D. 25
Every triangle adds up to 180 degrees so you just add up the given numbers, then subtract that number from 180 and that is your answer.
