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:
85.6cm
Step-by-step explanation:
Area of a triangle =1/2*b*h
Where base=19.5cm while the height is 8 4/5 = 8.8
Area = 1/2 * 19.5cm * 8.8cm
Area = 171.6cm/2
Area=85.6cm
Then c = 22 just keep adding 7
8+7=15 15+7=22
48.012001 is the answer to this problem
