Answer:
3 = 21 degrees
5 = 21 degrees
1 = 60 degrees
2 = 39 degrees
4 = 39 degrees
Step-by-step explanation:
This problem is really quite easy once you break it down. I assume you want an answer based on the attachment. If a triangle is Isosceles, then its bottom two angles are congruent, so angle 3 = angle 5.
Then, 138 degrees + x * 2 = 180 degrees.
x * 2 = 42 degrees
x = 21 degrees
So 3 and 5 are each 21 degrees
If a triangle is equilateral, then it is also equiangular, meaning each of its angles are equal to each other, and they are each 60 degrees. Then, we know angle 1 is 60 degrees. For 2 and 4, we want to take the measure of the combination of 2 and 3 (the full 60 degrees), and subtract it by the measure of angle 3 to get the measure of angle 2. 60 - 21 = 39 degrees. Angle 2 is 39 degrees. The same can be done with angle 5 and 4 because they are the same measurements.
Answer:
4,374
Explanation:
Given the sequence: 2, 6, 18, ...
If we study the pattern we observe that:

This is a geometric sequence with:
• The first term, a=2
,
• Common Ratio, r=3
The nth term of a geometric sequence is obtained using the formula:

Therefore, the 8th term will be:

The 8th term of the sequence is 4,374.
