Question

two poles AB and PQ are standing opposite each other on either side of the road 200m wide from a point R between them on the road angle of elevation of the top of the pole AB and PQ 45 degree and 40 degree respectively if height of ab = 80m find the height of pq correct to the nearest metre

Answer 1

here is your answer and mark me as a brain list

Answer 2

Answer:

Step-by-step explanation:

Tan 45= height of AB/BR

1 = 80/BR

BR = 80

Now,

Tan 40 = Height of PQ/200-80

O.8391= PQ/120

PQ =0.8391×120

PQ = 100.692

PQ ~~= 100.7m
