Answer:Either
9
+
(
k
−
17
)
or
(
9
+
k
)
−
17
depending upon what you meant by
"sum of 9 and k minus 17"
(the resultant value would be the same, but the expression would be different).

Answer:
∠ CDA = 32.3°
Step-by-step explanation:
See the given figure attached to this answer.
Draw perpendiculars from B and C on AD which is BE and CF.
Now, Δ ABE is a right triangle and AE² = AB² - BE² = 7.5² - 6² = 20.25
⇒ AE = 4.5 cm
Now, DF = AD - EF - AE = 24 - 10 - 4.5 = 9.5 cm {Since BC = EF}
And CF = BE = 6 cm.
Now, Δ CFD is a right triangle and
{Where β = ∠ CDA}
⇒ 
Degree.
So, ∠ CDA = 32.3° {Correct to one decimal place} (Answer)
Answer:
94.86 miles per hour
Step-by-step explanation:
The frigate bird has a top recorded speed of 153 kilometers per hour. How would you state this speed in the appropriate customary unit? (1 km = 0.62 mi)
The appropriate customary unit is calculated as:
1 km = 0.62 miles
153 km = x
Cross Multiply
x = 153 × 0.62 miles
94.86 miles
Therefore, the appropriate customary unit is 94.86 miles per hour
