Answer:
3x
Step-by-step explanation:



Answer:
y = 90°
Step-by-step explanation:
- 110° is the measure of exterior angle of bigger triangle.
- -> (x + x) + 70° = 110° (By exterior angle theorem)
- y is the measure of exterior angle of smaller triangle.
- -> y = x + 70° (By exterior angle theorem)
20x-10y=60 simplified would be y=2x-6
slope : 2
