sin(30°) = 4/x. Multiply both sides by x.
x * sin(30°) = 4. Divide each side by sin(30°).
x = 4/sin(30°). Solve for x.
x = 8.
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:
2x³+5x²+7x+5
Step-by-step explanation:
(x² + 4x² + x³ + x) + (x³ + x + 5x + 5)
(5x²+x³+x)+(x³+6x+5)
2x³+5x²+7x+5
55% if the percent is out of 100%. in which most weather statisics are out of 100. in which you take 100-45= giving you 55%
