Answer:
Step-by-step explanation:
The angle marks show that ΔRST is isosceles, so RT = RS. They also show ΔRTU to be equilateral, so UT = RT.
UT = RS
x -5 = 15
x = 20 . . . . . . add 5
__
ΔRTU is equilateral, so ∠RTU is 60°. The angle marked 3y° is complementary to that.
3y = 30
y = 10 . . . . . divide by 3
Median is described as the number in the middle of the set (given that the set is ordered from least to greatest), so we'll first order our set.
[48 49 50 52 54 62]
We notice that there is no middle number, so we take the two numbers that share the middle space and find their mean.
50+52=102
102/2=51
The median is 51.

hello
the answer to the question is option A
to solve a problem like this, let x represent the first number
x + (x + 1) = 17
x = first number
x + 1 = successive number
The prime numbers between 60 and 70 are 61 and 67.
