Answer:

60

Step-by-step explanation:

All triangles have a total measurement of 180 degrees. So to find the last angle measure subtract 90 and 30 from 180, 180-(90+30). This equals 60 degrees. Additionally, a triangle with a 90 and 30 degree angle is known as a 30-60-90 special right triangle. All of these triangles will have 60 as their third measurement.

Answer:

Think simple.

We already have parallelogram LENS, therefore:

∠L ≅ ∠ENS

We also have parallelogram NGTH, therefore:

∠T ≅ ∠GNH

Finally, we can also see that:

∠ENS ≅ ∠GNH (opposite angles)

=> ∠L ≅ ∠T
