Answer:
Half of 12 is 6(new radius)
6^2 = 36
36 x 3.14 = 113.04
113.04 x 8 = 904.32

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). 7 The measure of angle Ois 4. The measure of its reference angle is °, and tan is
The measure of the trigonometric relations is tan θ = -1 when the reference angle θ = 315°
What is Reference Angle?Every angle is measured from the positive part of the x-axis to its terminal line (the line that determines the end of the angle) traveling counterclockwise. For angles in the first quadrant, i.e., angles less than or equal to 90 degrees, the reference angle is equal to the original angle.
The reference angle is always positive
0° to 90°: reference angle = angle
90° to 180°: reference angle = 180° - angle
180° to 270°: reference angle = angle - 180°
270° to 360°: reference angle = 360° - angle
Given data ,
Let the reference angle be represented as R
Now , the value of R is R = 315°
And , the measure of angle θ = 7π/4
The reference angle θ = 315°
So , the value of tan ( 315 )° = -1
Hence , the trigonometric value tan ( 7π/4 ) = -1

3 √ 7 + √ 7 can someone elaborate this for me
Answer:
9.3
Step-by-step explanation:
Answer:
The answer is 4 \sqrt{7}.
Step-by-step explanation:
The formula is a\sqrt{x} + b\sqrt{x} = (a+b)\sqrt{x}, but if you don't understand it, here's an easier way to think about it.
You can think of \sqrt{7} as x (or any other variable). Now, the equation is 3x + x. If you've ever done algebra, (you probably have if square roots popped up on your homework) you know that this equals to 4x. Now, replace the x with \sqrt{7}, because we already decided that those two were equal. Therefore, the answer is
4 \sqrt{7}.

if 124 is subtracted from the square of a number the result is 200 what is the number
Answer:
x=18
Step-by-step explanation:
let the number =x
then
x²-124=200
x²=200+124
x²=324
x=18
Answer:
x=18
Step-by-step explanation:
number = x
x^2 - 124 = 200
x^2 = 200 +124
x^2 = 324
(square root both sides)
x = 18

Answer:
[tex]x=80^{\circ},\\y=80^{\circ}[/tex]
Step-by-step explanation:
The measure of an angle formed by a secant and a tangent outside of a circle is half of the absolute difference between the two arcs it forms. Therefore, we have the following equation:
[tex]m\angle A=\frac{\widehat{BC}-\widehat{BD}}{2}[/tex]
Substituting given values, we get:
[tex]20=\frac{120-x}{2},\\40=120-x,\\x=\boxed{80^{\circ}}[/tex]
Since there are 360 degrees in a circle, we can write the following equation, using [tex]x[/tex], to solve for [tex]\widehat{DC}[/tex]:
[tex]x+\widehat{DC}+120=360,\\80+\widehat{DC}+120=360,\\\widehat{DC}=\boxed{160^{\circ}}[/tex]
The value of the angle formed by a chord and a tangent is half the measure of the arc it forms. Therefore,
[tex]y=\frac{\widehat{DC}}{2}=\frac{160}{2}=\boxed{80^{\circ}}[/tex]

Hence, the approximate length of the ladder is [tex]12ft[/tex].
What is the approximation value?
An approximation is anything that is similar, but not exactly equal, to something else. A number can be approximated by rounding.
A calculation can be approximated by rounding the values within it before performing the operations.
Here given that,
[tex](x)^2=(11.5)^2+(3.5)^2\\X^2=132.25+12.25\\X^2=144.5 \\X=\sqrt{144.5}\\X=12 feet[/tex]
