Answer:
m<1 would 60° because the lines are congruent and parallel
This question belongs to Greatest common factor category.
Total number of pennies = 135
Total number of nickles = 225
So the greatest common factor is 45.
Hence,
Suyin can place pennies in a stack of 45 and there will be 3 stacks like that.
She can place nickles in a stack of 45 and there will be 5 stacks like that.
Answer:
m∠KJL = 54°
Step-by-step explanation:
In ΔJKL,
m∠JKL = 72°
JK ≅ KL
Since, two sides of ΔJKL are congruent, triangle is an isosceles triangle.
By the property of an isosceles triangle,
Opposite angles of the congruent sides of an isosceles triangle are equal in measure.
Therefore, ∠J ≅ ∠L
By the property of a triangle,
Sum of all interior angles of a triangle is 180°.
m∠J + m∠K + m∠L = 180°
m∠J + 72° + m∠J = 180° [Since, m∠J = m∠L]
2m∠J = 180° - 72°
m∠J = 54°
Therefore, m∠KJL or m∠J is 54°.
