If mAD=85 degrees and mBC=31 degrees find the value

Eddi Din [679]3 years ago

Answer: x = 11

To start, we know that a whole circle equals 360 degrees. If we subtract the 2 arcs we know, 85 and 31, we have 244 degrees left for the 2 congruent arcs. Dividing that by 2 gives us 122 for each arc.

Now, write the equation:  122 = 13x - 21

Solve this, to find the x = 11.

The nth term is 3n+2
poizon [28]

Answer:

5, 8, 11 and 32

Step-by-step explanation:

For the first 3 terms, substitute n = 1, 2, 3 into the n th term formula

a₁ = 3(1) + 2 = 3 + 2 = 5

a₂ = 3(2) + 2 = 6 + 2 = 8

a₃ = 3(3) + 2 = 9 + 2 = 11

Similarly for tenth term, let n = 10

a₁₀ = 3(10) + 2 = 30 + 2 = 32

you take 240 and subtract that from 2/5.Then you subtract 20 and that gives you 219.6.Since they have the same amount of marbles left,you have to divide 219.6 by 2 and your answer is 109.8

zimovet [89]

Answer:

Step-by-step explanation:

The sum of a triangle's interior angles is 180

. From the figure, we can see that one of the angles is a right angle. The remaining two are x and y. By adding these together, we can equate their sum with 180.

x+y+90=180b

Using the equation found in part A and the given equation, we can form a system of equations.
