Step-by-step explanation:
All the angles in a triangle add up to 180 degrees
x-22 + 3x+19 + x-17 = 180
x+3x+x-22+19-17=180
5x - 20=180
5x=180+20
5x=200
5x/5=200/5
x=40
Angle A= x-22
Substitute x in the question
= 40 - 22
=18
Therefore angle A is 18 degrees
Answer:
X Y
--------
1 0.50
2 0.25
3 0.13
4 0.06
5 0.03
I'd say multiply the numerators then the denominators and at the end simplify at least thats how I multiply fractions :)
Their LCM is
70
