In ΔBCD, the measure of ∠D=90°, the measure of ∠C=83°, and DB= 1.3feet. What is the length of CD to the nearest tenth of a foot.

Lina20 [59]

Answer:

$CD\approx0.2$

Step-by-step explanation:

By the tangent ratio, $tanC=\frac{DB}{CD}$ . Substituting the given values into this equation gives us:

$tan83$ ° $= \frac{1.3}{CD}$

$CD*tan83$ ° $=1.3$ (Multiply both sides of the equation by $CD$ )

$CD=\frac{1.3}{tan83\textdegree}$ (Divide both sides of the equation by $tan83\textdegree$ )

$CD=0.15962\approx0.2$

Hope this helps!

aniked [119]

Answer:0.625

Step-by-step explanation:

Given

There are two coins one is fair and another is bent

Probability of getting a head on fair coin is 0.5

Probability of getting a head on bent coin is 0.75

If both coins are tossed once

probability of getting at least one of the coin will come up tails is

$P=1-P(both\ heads)$

$P=1-0.5\times 0.75$

$P=1-0.375$

$P=0.625$
