Find the unknown angle measures.

Solution

To solve this problem, let's focus on the triangle provided. The angles given are:

  • Angle 1: 34°
  • Angle 2: 59°
  • Angle 3 (unknown, marked as z°)
  • Angle 4 (unknown, marked as y°)

Since it's a triangle, the sum of the internal angles of any triangle is always 180°.

Step 1: Calculate Angle zz

From the image, the triangle has angles 34°, 59°, and zz. We know that: 34°+59°+z°=180°34° + 59° + z° = 180° z°=180°34°59°z° = 180° - 34° - 59° z°=87°z° = 87°

Thus, the measure of angle zz is 87°.

Step 2: Calculate Angle yy

From the diagram, it appears there is an external angle formed with one of the sides of the triangle. We know that the external angle is equal to the sum of the two opposite interior angles. In this case, the exterior angle yy should be equal to the sum of 34° and 59°: y°=34°+59°y° = 34° + 59° y°=93°y° = 93°

Thus, the measure of angle yy is 93°.

Final Answer:

  • z=87z = 87^\circ
  • y=93y = 93^\circ
