324 square feet.
9 x 12 = 108 square feet.
3 walls x 108 sq. ft. = 324 sq. ft.
To find the base we will use the formula
base = Area/width
to plug in what we are given
base = 288/12
Base = 24 cm
Hope this helps :)
For 1:
Use pythagorean theorem because of the radius tangent theorem(point of contact = 90 degrees)
12 is the hypotenuse (the right angle points at the hypotenuse)
Therefore:
(9)^2 + (x)^2 = (12)^2
81 + x^2 = 144
Subtract 81 from both sides of the equation
x^2 = 63
Square root both sides to get rid of square on x and isolate the variable
The square root of 63 = 7.93 (roughly)
As the triangles are similar corresponding sides are in the same ratio
So we have:_
24/6 = (30-2x) /x
4x = 30-2x
6x = 30
x = 5
Answer:
The answer to this question is B) - 1 / 8.
