A triangle has three angles that measure 15 degrees, 85 degrees and (4x - 20). What is the value of x?
1 answer:
180=15+85+(4x-20)
180-15-85=4x-20
80=4x-20
4x-20=80
4x=80+20
4x=100
x=100/4
x=25

Answer:
$3.72
Step-by-step explanation:
7.75*2=15.5
15.5+0.78=16.28
20-16.28=3.72
subsitute x = 6 into the lengths
3(6) -7
18 - 7
11cm
(6) + 5
11cm
therefore it is a square when x = 6 because the sides are all equal
