So you find out how many triangles are in this by taking a point and making a line to another point that isn't on the same line. this one has 3 triangles. each triangle is 180*(using multiplication symbol for degree symbol).you do this to find out what the number of angles adds up to. 180* multiplied by 3 equals 540*. Then if you add up all the angles you have 400*. 540 - 400 equals 140*. So the final angle is 140*. Hope this helps!
Answer:
x = - 27/8

Step-by-step explanation:
¹²⁾x/5 - ¹²⁾1/5 = ²⁰⁾x/3 + ¹⁵⁾1/4
12x - 12 = 20x + 15
- 12 - 15 = 20x - 12x
- 27 = 8x
x = - 27/8

Answer:
1/27
Step-by-step explanation:
I believe the answer to your question is 1/27
I hope this helps you!
Since we know that percentages and decimals go by decimal place we can solve this. For Example, 10% is just 0.1, so if we apply this to the questions we can solve them
1) 49%
2)16%
3) Equal
4)12%
5)1.2
6)31/50
7)50 1/4
8)1/8
