Step-by-step explanation:
The way your problem is set it should be simplified to this....4x + 55
Answer:
1. 63
2. 49°
3. 87°
4. 44°
Step-by-step explanation:
First, I worked out Angle 3 as this angle and 93° are on a straight line:
So I made an equation:
180 = 93 + Angle 3
180-93 = Angle 3
87 = Angle 3
Now we have enough information for Angle 4 as angles in a triangle add up to 180
87 + 49 + Angle 4 = 180
Angle 4 = 180 - 87 - 49
Angle 4 = 44
Using the rule of opposite angles:
I worked out that Angle 2 must be 49 as well.
This is now enough information to work out Angle 1 as angles in a triangle add up to 180
49 + 68 + Angle 1 = 180
Angle 1 = 180-49-68
Angle 1 = 63
