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°

225/5 = 45
This means the parents gave her five dollars forty five times. If they gave her a five every time she saved one dollar, you just have to multiply the money she saved each time and the number of times she saved it, and you'll get the answer.
Wendy saved $45 by herself

Write the equation of a line perpendicular to 5x - 7y =-6 that passes through the point (-5,6)

Likurg_2 [28]

9514 1404 393

Answer:

7x +5y = -5

Step-by-step explanation:

You can find the perpendicular line by swapping the x- and y-coefficients, and negating one of them. The new constant can be found by using the given point.

7x +5y = 7(-5) +5(6) = -5

The perpendicular line through (-5, 6) is ...

7x +5y = -5

A spinner has 12 equal sections:5 red 4 green and the rest are black. In 921 spins how many times can you expect to spin black?

Komok [63]

Answer:

230

Step-by-step explanation:

12 sections total

5 red, 4 green, the rest black

12-5-4 = 3 sections are black

3/12 = 1/4 of the sections are black

1/4 represents the probability of landing on black for one spin

(1/4)*921 = 230.25 which rounds to 230

We expect to land on a black section about 230 times out of 921 times total.

ANSWER

$( {x - 11)}^{2} + ( {y - 5)}^{2} = 16$

EXPLANATION

The given circle has center:

(11,5)

and

radius: 4

The equation of a circle with center (h,k) and radius , r is given in standard form as;

$( {x - h)}^{2} + ( {y - k)}^{2} = {r}^{2}$

We substitute the values into the formula to obtain,

$( {x - 11)}^{2} + ( {y - 5)}^{2} = {4}^{2}$

$( {x - 11)}^{2} + ( {y - 5)}^{2} = 16$
