Step-by-step explanation:
Answer:
This looks like homework so you should try to figure it out yourself.
Step-by-step explanation:
The triangle CID will be the same as triangle 21KG and the triangle ABH will be the same as JFE because they are both directly proportional to each other.
Answer: 3xy+5y−1
<u>Combine like terms</u>
3xy+−4+−2y+7y+3
(3xy)+(−2y+7y)+(−4+3)
3xy+5y+−1
Angle 2 + Angle5 = 90° (Because angle 1 + angle 2 + angle 5 = 180°)
Angle 2 = 60°



[since, vertically opposite angles]
Angle 4 + Angle 3 = 180°
Angle 3 = 180 - 30
Angle 3 = 150°
Have a nice day!
