The dimensions of the pool is 15m by10m
<h3>Area and perimeter of rectangle</h3>
A pool is rectangular in nature. If a rectangular swimming pool has an area of 150 square meters and a perimeter of 50 meters, then;
lw = 150
2(l+w) = 50
l + w = 25
where
l is the length
w is the width
From the equation 3
l = 25 - w
Substitute into 1
(25-w)w = 150
25w-w² = 150
w²-25w+150 = 0
w²-10w-15w+150 = 0
Factor
w(w-10)-15(w-10) = 0
w = 10 and 15
l = 150/10 = 15
Hence the dimensions of the pool is 15m by10m

In a triangle, the three interior angles always add to 180°
m∠B = 180 - 30 - 80 = 70°
<span>D: 70</span>
I think it is c hope it helps
Billy, let's recall what a linear pair of angles is:
• They are formed when two lines intersect.
,
• Two angles are said to be linear if they are adjacent angles formed by two intersecting lines.
,
• The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Upon saying that we have that:
• CAD and DAE are linear pairs
,
• CAD and CAB are linear pairs
,
• DAE and BAE are linear pairs
,
• DAE and DAC are linear pairs
Now, you are ready to select all the options that actually apply.
