Since all three sides are different lengths and angles, that triangle would be considered an Isosceles triangle.
150 miles= in 3 hours
150 miles/3 hours
= 50mph
8 (2x - 14) + 13 = 4x -27
distribute 8 through the parentheses
16x - 112 + 13 = 4x - 27
combine like terms
16x - 99 = 4x -27
subtract 4x from each side
12x - 99 = -27
add 99 to each side
12x = 72
divide each side by 12
x = 6
A - This is the same as : (3*3*3*3)/4 Wrong.
B - This is 12/4 Wrong.
C- This is 3/2 * 3/2 * 3/2 * 3/2 Correct.
Add the 75 and 79 which gives u 154
then subtract it by 180 and should give you 26 as your final answer
