Congruent sides, so isosceles triangle. When we have an isosceles triangle the bisector of angle A is a perpendicular bisector of BC with foot D. So x=ADB=90 degrees.
Angle B is 47 degrees and angle y=BAD is complementary, the other acute angle in a right triangle.
y = 90 - 47 = 43
Answer: x=90, y=43

Step-by-step explanation:
Answer:
15 km/h
Step-by-step explanation:
To find the speed, divide the total number of kilometers by the total number of hours:
Find the total number of hours:
32 + 13
= 45
Divide this by 3:
45/3
= 15
So, the average speed was 15 km/h
