Answer:
Step-by-step explanation:
∠5 +∠6 +∠7 = 180 {straight line angle}
38 + 62 + ∠7 = 180
100 +∠7 = 180
∠7 = 180 - 100
∠7 = 80°
l // m
∠3 = ∠7 {Alternate interior angles are congruent}
∠3 = 80°.

Answer:
By the Pythagoras theorem, the hypotenuse (c), is equivalent to:
a^2+ b^2= c^2 where a and b are the other two sides of the right angled triangle, hence c= square root (15^2+ 20^2)= 25
I think the answer might be 72
