The measure of triangle ABD is 50°

Step-by-step explanation:

Given:

Triangle ABD is formed by tangent and secant

minor arcs AC=68°, CD=124°

To find:

the measure of triangle ABD

Solution:

Angle Formed by Tangent and Secant = 1/2*(difference of Intercepted Arcs)

The intercepted arcs are AC and AD.

We know that minor arc AC + minor arc CD + minor arc AD = 360°

So using this formula AD = 360° - minor arc AC - minor arc CD

AD = 360° -68°-124°

arc AD = 168°

Substituting in the above formula,

∠ ABD = 1/2*(minor arc AD - minor arc AC)

∠ ABD =1/2*(168 - 68)

∠ABD= 50°

Can you write the equation for a circle if the given point does not lie on the circle? Explain .

Pachacha [2.7K]

Answer:

Step-by-step explanation:

The equation of a circle with center (a,b) and radius r is given as:

${(x - a)}^{2} + {(y - b)}^{2} = {r}^{2}$

If a given point (x,y) does not lie on this circle, it will not satisfy its equation.

This means the distance from the point to the center is not equal to the radius.

It is either less or greater than the radius.

Hence you cannot write the equation of the circle.

I will use fancy gold and red wrapping paper for two packages i have to wrap. I will use 1 2/4 yard of paper for one of the boxe

Allisa [31]

Well you need first 1 2/4 of a yard. Then you will need 5/6 of a yard. But first you need to put them together. So we need to find the common denominator. Six and four both share which multiple? Twelve. So let's rewrite that. You need 1 6/12 yards + 10/12 yards of wrapping paper. But before we do anything else we need to fix the mixed number. 1 6/12 isn't as easy to add ad 18/12 is. So 18/12 + 10/12 = 28/12
That can simplify as well. Now it's 14/6 which is equivalent to the fraction we had before. But it can also go down to 2 2/6. Now we can simplify it even further. By dividing it by two we can get 2 1/3. These are the measurements we need. So you would need how many thirds? Seven. (2 1/3 is seven thirds) This is your final answer.

You would need to have seven peices of wrapping paper cut to wrap both gift boxes.

The sum of two consecutive integers is -15. Which equation could you use to find the two integers and what is the smaller intege

PtichkaEL [24]

Answer:

-8

Step-by-step explanation:

x+x+1= -15

2x+1=-15 (group the x's together)

2x= -14 (move the 1 to the right side)

x= -7

(-7)+(-8) = -15

-8 is the smaller integer

Triangle L N M is shown. Angle L N M is 90 degrees and angle N M L is 20 degrees. The length of L N is 21.

horsena [70]

Angle L: 70°

The trigonometric ratio used to solve for NM is the tangent ratio.

NM = 57.7 [nearest tenth]

<h3>How to Apply the Trigonometric Ratios?</h3>

Using the triangle sum theorem, find angle L.

Angle L = 180 - 90 - 20 = 70°

Using the tangent ratio, we can use ∠M and LN to solve for NM

Tan 20 = 21/NM [tan ∅ = opposite/adjacent]

NM = 21/tan 20

NM = 57.7 [nearest tenth]
