Firstly, we will draw diagram
we will draw line qq'
which will make mqq'n as parallelogram
and we know that opposite sides of parallelograms are always equal
so, we get
we are given
mq=42
so,
we can see that q' lies on np
so, we can write as
we are given
np=112
so, we can plug these values
now, we can see that
triangle qpq' forms isosceles triangle
so, we get
so,
............Answer
Answer:
x ≈ 25.4 Km
Step-by-step explanation:
Using the tangent ratio in the right triangle on the right
tan54° = =
( multiply both sides by 17 )
17 × tan54° = opp , thus
opp ≈ 23.4
-------------------------------------------
Using the cosine ratio in the right triangle on the left
cos23° = =
( multiply both sides by x )
x × cos23° = 23.4 ( divide both sides by cos23° )
x = ≈ 25. 4 Km ( to the nearest tenth )
