Answer:
vertical angles theorem
3x + 4 = 49
Step-by-step explanation:
Lin's number = l
pazi's number = p
l = p + 7
p = p
p + 7 + p = 49
2p + 7 = 49
2p + 7 (-7) = 49 (-7)
2p = 42
2p/2 = 42/2
p = 21
l = p + 7
l = 21 + 7
l = 28
pazi is 21 years old, Lin is 28 years old
hope this helps

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.
