Answer:
It's not Right Angled Triangle.
Step-by-step explanation:
By using Pythagoras theorem.
H^2=P^2+B^2
Here p=2,b=3,and h=4.
4^2=3^2+2^2
16=9+4
16 is not equal to 13.
Proved.
Circumference one = (2R)*pi let that value be 2x
C second = 5x = (2R)*pi * 5 / 2 = (5R)*pi
So Radius one / Radius two = 2 / 5
Area1:Area2=pi(2R)^2:pi(5R)^2=pi(4R^2):pi(25R^2), pi cancel out we get
4R^2:25R^2, now R^2 cancel out and we get ratio of
4:25

Answer:
1.) 163
2.) 56
3.) 94
Step-by-step explanation
Because the angles are supplementary, it means they equal 180 degrees. Therefore, just use this equation to found the unknown angle.
180-(The Number you are given) = (The angle you want)
For Example,
180-86=94
