Angle c and angle d are congruent. Congruent means they have the same the measure, or they have EQUAL measures. You set the two values equal to each other and solve for x.
X+26=2x-10 subtract x from both sides
26=x-10 add 10 to both sides
36=x
Now substitute x back in for angle d.
2(36)-10 = 62
Answer:
Option C.
Step-by-step explanation:
Let as consider parallel lines r and s are cut by transversal q. On line s where it intersects with line q, the uppercase left angle is 125 degrees and the bottom right angle is d degrees.
We need to find the value of d.
If a tranversal line intersect two parallel lines, then the alternate exterior angles are equal.
Uppercase left angle and bottom right angle are alternate exterior angles. So we can say that
d = 125°
Therefore, the correct option is C.
Answer:
Option: D is the correct answer.
D) 4
Step-by-step explanation:
A random draw is being designed for 210 participants.
If the winner is to be drawn using 10 balls numbered 0 through 9.
That is for the 210 participants we have to get a 210 unique numbers so that each participant winning chance is denoted by a unique number.This means that n balls are to be drawn out of the 10 balls such that we get total 210 choices irrespective of their order.
Hence, we have to find n such that:

A)
Now when n=10
we have:

Hence, option:A is incorrect.
B)
when n=6 we have:

C)
n=5

D)
n=4

So, either 4 or 6 balls can be drawn in order to obtain 210 choices but we are asked to find the minimum number of balls and as 4<6 .
Hence, a minimum of 4 balls need to be drawn so that each receives a unique number.
