Given:
A figure of a right triangle.
To find:
The missing side by using the trigonometric ratios.
Solution:
In a right angle triangle,

In triangle ABC,



Multiply both sides by 270.



Therefore, the missing side length is b=231.4 inches.

how to try the values of the x and y
(x,y)
G: the solutions are x=2; x=3; x=-4; and x=-6. None of the answers are the same.
Answer:
l=20m
w=5m
Step-by-step explanation:
Let "l" be the length of the rectangle &
let "w" be the width of the rectangle
l=15+w
P=2(l+w)
50m=2(15m+w+w)
50m=2(15+2w)
50m=30m+4w
20m=4w
w=5m
l=15m+w
l=15m+5m
l=20m
Proof:
P=2(l+w)
P=2(15m+w+w)
50m=2(20m+5m)
50m=40m+10m
50m=50m
