Answer:
You need to put the link on which is like the paper clip before you post.
Step-by-step explanation:
54.Angle A=70°
Angle B=Angle A
Angle B=(3x+7)°
3x+7=70
3x=63
x=63/3
x=21
55.4x+3=45
4x=42
x=10.5
9.9 squared is close to 10 squared therefore it is 100
100×1.79= 179
The second one? Sorry if you get it wrong I’m not really sure! :3
