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:
a2 = 12
a3 = 36
Step-by-step explanation:
Terms of a geometric sequence have a common ratio. If we call that ratio r, then we have ...
a2 = 4r
a3 = (a2)r = 4r^2
108 = (a3)r = 4r^3
27 = r^3 . . . . . . . . . . . divide by 4
3 = r . . . . . . . . . . cube root
__
a2 = 4(3) = 12
a3 = 12(3) = 36
1/2 = 50%
3/4 = 75%
So something in between that could be 2/3 (which equals 66.67% )
A few others could be: 3/5 ( equals to 60% ) , 7/10 ( equals 70%)
Hope that helps :)

Answer:
23.4 units
Step-by-step explanation:
Given the point of the vertices of triangle ABC as A(−5,1), B(2,1), and C(6,4).
The distance (d) between two points X (x₁ , y₁) and Y(x₂, y₂) is given as:
. We can use this to calculate the length of the sides of the triangle. Therefore:

The perimeter of the triangle ABC = AB + AC + BC = 7 + 11.4 + 5 = 23.4 units
