Answer:
A. 54°
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
y + y + 72 = 180
2y + 72 - 72 = 180 - 72
2y = 108
(2y)/2 = 108/2
y = 54
Answer:
Seven hundred and eighty-five
Answer:
No
Step-by-step explanation:
because 2 is divisible by 14 but 4 is not divisible by 17
Answer:
J=40º, K=60º, H=80º
Step-by-step explanation:
since all angles of a triangle add up to 180º, we can make an eqaution.
3x+2x+4x=180
9x=180
x=20
J=2x=20x2=40º
K=3x=20x3=60º
H=4x=20x4=80º
