Answer:
The answer would be false.
Step-by-step explanation:
Not all angles are going to add up to be greater than 90 degrees. say you have two angles that both measure to be 30 degrees, when they are added, they do not equal 90. Hope this helped!
Answer:
Step-by-step explanation:

i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point.
So t is perpendicular to JL
let l be the tangent line through L. Then l is perpendicular to JL
ii. So t and l are 2 different lines, both perpendicular to line JL.
2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.
Remark. Draw a picture to check the steps
Answer:
A. 8π cm; 16π cm2
Step-by-step explanation:
circumference: C = 2πr = 2(4)π = 8π cm
area: A = π(r^2) = (4^2)π = 16π cm^2
