Step 1
Since we are given the lengths of all three sides, we can use the Law of Cosines to find the angle measures. The Law of Cosines states that in a triangle with sides a, b, and c, and angle C opposite side c, the following equation holds: c^2 = a^2 + b^2 - Show more…

In the figure below, the measure of angle ∠1 = 4x°, the measure of angle ∠2 = y°, and the measure of angle ∠3 = 72°. Find the value of each variable. A line that rises from left to right intersects a line that falls from left to right, forming four angles. Three of these angles are labeled as follows in clockwise order from the left: 1, 2, 3. x =
