Step-by-step explanation:
since they are congruent triangles, all your have to done is the compare the longest side of the first triangle is equal to that of the other; the smallest side of the first triangle is equal to that of the second, and so for the corresponding angles
using the above method,
Answer:
a) from mere observation line PQ is the longest therefore it is equal to the length of the longest side of the other triangle. so line PQ = 9
b) again, ang PQ is the smallest, using the method, ang PQ = 46 degrees
but mind you, you could use a ruler to measure the length to find the longest more accurately.
