If the ratios are 2:12:16 the equation that should be used is 2x + 12x + 16x = 180.
First solve for x:
2x + 12x + 16x = 180
30x = 180
x = 6
Then plug x back in to find the degrees for each angle:
2x = 2(6) = 12
12x = 12(6) = 72
16x = 16(6) = 96
These are the degrees for each triangle: 12 degrees, 72 degrees, and 96 degrees which adds up to 180 degrees in total.
The equation, also at the top, is 2x + 12x + 16x = 180.
Answer:
the answer is d
Step-by-step explanation:
It is A, 60° because 180° (degree of the whole triangle) divided by the three angles is 60.
16.4
20.5/5=4.1
4.1*4=16.4
