Answer:
Explanation:
4x + 2x = 180 degree
6x = 180
x = 180/6
x = 30
Therefore, x = 30 degree
Answer:
1. x=40
2. x=17
3. x=5
4. x=83
Step-by-step explanation:
It is a similar triangle so the side length of the smaller triangle (x and x-2) are in the same ratio as the bigger triangle (2x+5 and 2x-1). As the ratio is the same, you can equate them and solve for x.
