Answer:
Step-by-step explanation:
(Tangent Length)^2 = y*(y + 11) You are going to have to use the quadratic formula on this.
Tangent Length = 7
7^2 = y * (y + 11)
49 = y^2 + 11y
0 = y^2 + 11y - 49
a = 1
b = 11
c = - 49
When you solve this quadratic equation you get
x1 = 3.40 which is the answer you go with.
x2 = -14.40 which can't be used. A negative length has no meaning.
Divide both 6 and 10 by 2 to get 3/5
Multiply both 6 and 10 by 2 to get 12/20
Answer:
132 degrees
Step-by-step explanation:
x+ 3+7x-15=180
8x -12 =180
8x = 168
x=21
7(21) -15
147-15
132
The volume of the rectangular box is 12 cubic inches
<h3>Volume of a box</h3>
The formula for measuring the volume of a rectangular box is expressed as:
V = lwh
l is the length
w is the width
h is the height
Given the following
l = 2in
w = 3in
h = 2in
Substitute
V = 2* 3 * 2
V = 12 cubic inches
Hence the volume of the rectangular box is 12 cubic inches
