Number C. because it is and acute angle, and all the measures are less than 90°
Let x = TJ's current age.
Therefore each of the three has the same age.
Because the sum of their ages is s, therefore
3x = s
x = s/3
TJ's age 8 years ago is s/3 - 8
Answer: s/3 - 8
Answer:
204.2 cm
Step-by-step explanation:
equilateral means all sides are of equal length.
the perimeter of such a triangle is simply 3 times one of these sides.
so,
612.6 = 3×0.2×(10x + 90) = 0.6×(10x+90) = 6x + 54
6x = 558.6
x = 93.1
so, a single side is
0.2×(10×93.1 +90) = 0.2×(931 + 90) = 0.2×1021 = 204.2 cm
to check
3×204.2 = 612.6 = the original perimeter.
so, correct.
Y = 3, as the slope of VW is y = -1/5x - 2
