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
10 to the 2nd power only means 10x10=100
35.6/100=0.256
35.6/10x10=0.256
Answer:
x = 24, PR = 404, QS = 404
Step-by-step explanation:
PR and QS are both diagonals of the rectangle. The diagonals of a rectangle bisect each other and are of equal length. Thus, we can say:
PR = QS
18x - 28 = x + 380
Solving for x, we get:
18x - x = 380 + 28
17x = 408
x = 408/17
x = 24
Thus, PR = 18(24) - 28 = 404 and QS = 24 + 380 = 404
Third choice is right.
