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:
D
Step-by-step explanation:
no reason for the question to include his age
Answer:
y * ((h * x) + 15)
Step-by-step explanation:
l (Lawns)
h = hours
x = number of hours
y = number of lawns
y * ((h * x) + 15)
It doesn't have to be called width
So just use the formula.
A=h×w
A=2×8.5
A=17
The area of the rectangle is 17 meters
He would need to sell 28 because
12.50*28=350 and 350+50=400
