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: can't get enough info.
a = 11
Step-by-step explanation:
a + 15 = 3a - 7
-a -a
15 = 2a - 7
+7 +7
22 = 2a
/2 /2
11 = a
The factored answer is:
(x + 3)(3x - 4)
Answer:
12
Step-by-step explanation:
4(13+2)
=4(1+2)
=(4)(3)
=12
Answer:
The answer is A.
Step-by-step explanation:
This is Associative Law, a + (b+c) = (a+b) + c .
