Answer:
A, D
Step-by-step explanation:
When solving for x, we want to get all x terms on one side and all non-x terms on the other side. To make it so that x is by itself, we need to get rid of -3. We can do this by adding 3 to both sides, which demonstrates the addition property of equality. This property states that if you add a quantity to one side of an equation, you must add the same quantity to the other side as well.
Pie r squared is the area of a circle, so 9^2(3.14etc) = so 255 square yards. So 255 x 15 = $3,825
The trigonometric ratios of the right triangle with the given value tan A = 9 / 40 are
sin A = 9 / 41
cos A = 40 / 41
<h3>Trigonometric ratios</h3>
Trigonometric ratios are used to solve for the sides and angles of a right angle triangle.
Therefore,
sin A = opposite / hypotenuse
cos A = adjacent / hypotenuse
tan A = opposite / adjacent
Using Pythagoras theorem, let find the hypotenuse side
c² = 40² + 9²
c = √1681
c = 41
Therefore,
sin A = 9 / 41
cos A = 40 / 41

Given:
Measure of arcs 50°, 115° and 85°
To find:
The measure of the numbered angle 5.
Solution:
Let the missing arc measure be A.
The arc measure of a full circle is 360°
m(ar A) + 50° + 115° + 85° = 360°
m(ar A) + 250° = 360°
Subtract 250 from both sides.
m(ar A) = 110°
<em>If two chords intersects inside a circle, then the measure of the angle formed is half of the sum of intercepted arcs.</em>
The measure of the numbered angle is 112.5°.
Step One
Solve for CE as a numerical value
CE = 1/2 * CD = 1/2 66 = 33
CE = 33
Step Two
Solve for x
CD also equals x^2 - 3 which is given.
x^2 - 3 = 33 Add 3 to both sides
x^2 = 33 + 3
x^2 = 36 Take the square root of both sides
sqrt(x^2) = sqrt(36)
x = 6
Step 3
Find the length of AE
AE is given as 6x - 10
x = 6
AE = 6*6 - 10
AE = 36 - 10
AE = 26
Step 4
Find AB
AE = 1/2 AB Definition of bisect
26 = 1/2 AB Multiply by 2
2*26 = AB
AB = 52 <<<<<<<<Answer
