The measure of triangle ABD is 50°                                                                                                                          

<u>Step-by-step explanation</u>:

<u>Given</u>:

Triangle ABD is formed by tangent and secant

minor arcs AC=68°, CD=124°

<u>To find</u>:

the measure of triangle ABD

<u>Solution</u>:

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°

Which coordinate pair is the best estimate of the point of intersection in this graph?
alexandr402 [8]

Answer:

A

Step-by-step explanation:

The intersection is made when the red and blue line meet. If you make a mark down that looks like 1.5 and if you go up to your y axis the coordinate is 3/4 around the one since it is not over the one.

Find the x-intercepts (solve for x) for the following AND PLEASE SHOW YOUR WORK! y=−2x^2−9x+5
frosja888 [35]

Answer:

see explanation

Step-by-step explanation:

To find the x- intercepts set y = 0, that is

- 2x² - 9x + 5 = 0

To factorise the quadratic consider the factors of the product of the coefficient of the x² term and the constant term that sum to give the coefficient of the x- term.

product = - 2 × 5 = - 10 and sum = - 9

The factors are - 10 and + 1

Use these factors to split the middle term

- 2x² - 10x + x + 5 = 0 ( factor the first/second and third/fourth terms )

- 2x(x + 5) + 1(x + 5) ( factor out (x + 5) )

(x + 5)(- 2x + 1) = 0

equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

- 2x + 1 = 0 ⇒ x = \frac{1}{2}

x-intercepts are x = - 5 and x = \frac{1}{2}

15 POINTS PLEASEE SOMEOKE HELP ME WITH THIS
attashe74 [19]
Imagine each horizontal line as 180 degrees. So if your angle measure on the top right is 81 the other side of that will be 99 degrees and then you can apply vertical angles. Since angle two is a vertical angle to the degree measure of 81 it is also 81. Which means angle three is equal to angle 1, which is 99 degrees. Now since the horizontal lines are parallel the same angle measure will apply to angles 4,5,6, and 7

Final answer angles 1,3,4,7 are 99 degrees
And angles 2,5,6 are 81 degrees
