Answer: 77°
<u>Step-by-step explanation:</u>
In relation to ∠X, 3 is the adjacent side and 13 is the opposite side.
These drawings depict the steps to get the perpendicular line using a compas (and maybe a ruler)
remember that a line goes through 2 points so we need 2 different points to construct our perpendicular line
the first one is wrong because it doesn't constraint it to be perpendicular
it only has 1 point,
2nd is wrong as well, has only 1 point, the center
3rd is right
4th is correct, hold a sec
how did that 2nd upper arc have same beginig pointn for compass?
3rd on is answer
well, it's isosceles so use base angles theorem
the top angle is also x
90 + 2x = 180
subtract 90 from both sides
2x = 90
divide both sides by 2
x = 45 degrees
