The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
We are given
we know that
so, we get
opposite =7
adjacent=24
now, we can find hypotenuse
now, we can draw triangle and then switch vertices accordingly
we can find cos(B) using second triangle
In second triangle:
adjacent=7
hypotenuse =25
so, we get

Answer:
x = 120
y = 30
Step-by-step explanation:
Given that RST is equilateral, each of its interior angles will be 60 degrees
Looking at x, it lies on a starting line with one of the interior angles of RST
The sum of angles on a straight line is 180
Thus;
x + 60 = 180
x = 180-60
x= 120
Looking at triangle RSU, the markings indicates that we have an isosceles triangle
For an isosceles triangle, the base angles are equal in value
This means that SRU is also y
Mathematically, the sum of angles in a triangle is 180
Hence;
x + y + y = 180
x + 2y = 180
120 + 2y= 180
2y = 180-120
2y = 60
y = 60/2
y = 30
