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.
Answer:
The linear equation 6x + 8y = 72 is written in standard form.
Step-by-step explanation:
Standard form is .
- The answer is not D, because the equation given is not in slope intercept form. We can also take out A, and C too, because it is not close to that form.
- The answer is B, because the equation matches the standard form formula: , where A=6, B=8, and C=72

Answer:
Step-by-step explanation:
(x+6)(x+4)(x-3)
= [(x+6)(x+4)](x-3)
= (x² + 4x + 6x + 24)(x - 3)
= (x² +10x + 24)(x - 3)
= x³ - 3x² + 10x² - 30x + 24x - 72
= x³ + 7x² - 6x - 72
