Question

(v) find AB & BM
if you answer correctly i will mark u as brainalist​

Answer 1

What is 45 degree angle and what is 30 degree angle.

Please

Give the diagram properly.

Answer 2

Let height be NM=1500m

Angle BNM=90°-45°

=45°

This means third angle is 45°

......(sum of all angle triangle is 180°)

By trigonometry

tan∅=tan45°

1/1=1500/BM

BM=1500m

angle ANM=60°

This means third angle is 30°

.........(sum of all angle of triangle is 180°)

By trigonometry

tan∅=tan30°

√3/1=1500/AM

AM=1500/√3

=1500/√3 × √3/√3

=[1500×√3]/3

=500×√3

=5×100×√3

=5×√(3×100×100)

=5×√30000

=√(30000×5×5)

=√750000m

But this does not have root and it is very big.

So final answer will be 500√3

AB=AM-BM

=500√3-1500

≈1098.08m

Answer:-

$AB=1098.08m$

$BM=1500m$
