Answer:An inverse operation are two operations that undo each other addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality. This gives us a couple of properties that hold true for all equations i guess a little bit of fraction might help if im right idk but forget the fraction part just read the other.
Step-by-step explanation: thats all i got.

Answer: x = 29</h3>
======================================================
Work Shown:
x+61 = 90
x+61-61 = 90-61
x = 29
------------
Explanation:
- The first step is valid because the two angles x and 61 are complementary angles. They form a right angle or 90 degree angle.
- In the second step, I subtracted 61 from both sides to undo the "+61".
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
