Answer: x= 19
Step-by-step explanation:
RS =~ ST presumably reads segment RS is congruent to segment ST, i.e. the same length.
Then the triangle is isosceles, and angle SRT = angle STR. Angle STU = 180-angle STR.
SRT = 3x - 48, STU = 9x, so STR = 180-9x
SRT = STR
3x - 48 = 180 - 9x
3x + 9x = 180 + 48
12x = 228
x = 19

Answer:
x ≈ 17.3
Step-by-step explanation:
The triangles are all similar, so the side lengths are proportional.
short side / hypotenuse = x/30 = 10/x
x² = 300 . . . . . . cross multiply
x = 10√3 . . . . . . take square root
x ≈ 17.3
Answer:
may be the answer is g(4a)
Step-by-step explanation:
g(4a) = 2/(4a +3)
't' is replaced by '4a'.
The equation is 138=300-3x
now solve by first subtracting 300 from each side: -162=-3x
divide each side by -3: x=54
