5/12 - 3/20
=(5/12)x5 -(3/20)x3
=25/60 -9/60
=16/60
=8/30
Just make the denominators the same and u can get the answer easily
Hope I can help u:)
Answer:
Height of the tree is 40.0 meters.
Step-by-step explanation:
From ΔABC,
m∠ABC = 90°
Since, m∠ABC = m∠CBD + m∠ABD
90° = 6° + m∠ABD
m∠ABD = 90°- 6° = 84°
By triangle sum theorem in ΔABD,
m∠ABD + m∠BDA + m∠DAB = 180°
84° + 29° + m∠BDA = 180°
m∠BDA = 180° - 113°
= 67°
By sine rule in ΔABD,
h =
h = 39.98
h ≈ 40.0 meters
Therefore, height of the tree is 40.0 meters.
B = CA
