Answer 1
The measure of angle ABC is equal to ABD + CBD. If you have the measure of ABC and CBD, then you can subtract CBD from ABC to get the measure of ABD. Proof below:
ABC = ABD + CBD
subtract CBD from both sides
ABC - CBD = ABD

A spinner has 8 equal sectors with different letters for each sector, as shown below:

A spinner with 8 equal sectors is shown. The sectors are labeled B, Y, G, P, O, V, M, and R.

Hamlet spins the spinner 13 times, and it stops at the letter R 9 times. If he spins the spinner a 14th time, what is the theoretical probability that this time it will stop at the letter R?

Answers

Answer:

The theoretical probability of obtaining letter 'r' at the 14th spin is:

1/8

Step-by-step explanation:

It is given that:

A spinner has 8 equal sectors with different letters for each sector.

The sectors are labeled b, y, g, p, o, v, m, and r.

Hamlet spins the spinner 13 times, and it stops at the letter r 9 times.

We are asked to find the theoretical probability that we will get  letter r at the 14th spin.

The theoretical Probability is given as the ratio of number of favorable outcomes to the total number of outcomes.

Hence, the theoretical probability of obtaining letter 'r' at the 14th spin is:

( As there are a total of 8 outcomes( or 8 sectors) out of which there is only one sector which is red)

Hope this helped

only simplify, don’t solve please. thank you!

Answers

Answer:

4x

Step-by-step explanation:

the -8 and +8 cancel out

x and 3x are both positive so add them

you're left with 4x

Simplifying is the same as solving this question. I'll give steps instead.

x - 8 + 3x + 8

x + 3x - 8 + 8       (Arrange the equation)

(x + 3x) (- 8 + 8)   (Parentheses the like terms together)

(4x) (0)                 (Solve)

4x                        (Simplified)

I need answer to this question.
Explain why triangle ABC is congruent to triangle FED.
​

Answers

Answer:

The two angles of ΔABC are equal to the two respective angles of ΔFED. Also, the sum of all interior angles of a triangle is 180º. Therefore, third angle of both triangles will also be equal in measure.

Both triangles have right angles. Also the the two dashes on BC and DE indicate that those 2 sides of the triangles are the same. Angle A and angle F are also the same. This is what makes the triangles congruent
