Given the area and the lngth, find the width by div. the area by 6:
12x + 15 4x + 5
width = -------------- = ------------
6 2
Because the problem represents right angle we can use simple geometric functions to determine size of sides of triangle and its angles if needed.
Since we have angle at point that is 42 feets away from base of the building and we need lenght of side that is oposite from that angle that means that we need some trigonometric function that includes those 2 sides.
that function is tangens.
tan67 = oposite side/side next to angle
tan67 = x/42
x = 42*tan67
x = 98.94 feet
Answer is D 99 feet
Add 6 subtract 7 then multiply and put together
Answer:
<h3>Area of shaded region = 6.88 square inches</h3>
Step-by-step explanation:
Area of shaded region
When we subtract the area of the circle from the area of square, we get the area of the 4 corners. When we divide that by 2, we get the area of 2 corners(shaded).
<h3>Square: </h3>
Area of square = side *side
= 8 * 8
= 64 square inches
<h3>Circle:</h3>
diameter of the circle = side of the square
d = 8 in
r = 8/2 = 4 in
Area of circle = πr²
= 3.14 * 4 * 4
= 50.24 square inches
