Answer:

1. alternating interior angles

2. 60°

Step-by-step explanation:

1. By definition of <em>Alternating Interior Angles</em>, the angles must be located in between the parallel lines, and opposite of each other (hence alternating). The measurements of the two angles are exactly the same.

2. Since the angle measurements of Alternating Interior Angles are the same, x would = 60° as well.

Troyanec [42]

Pythagorean theorem is $a^{2} + b^{2} = c^{2}$
and using that sin is opposite/hypotenuse, you can find the third side of the triangle.
$11^{2}+(adjacent)^{2} = 61^{2} \\ 121+ (adjacent)^{2} = 3721 \\ (adjacent)^{2}=3600 \\ adjacent = 60$
now you know adjacent is 60, so cos=60/61
