Determine if "h=3" is a solution. 3h=2(h+2)-1

lutik1710 [3]

Answer:

Yes is a solution

Step-by-step explanation:

3h = 2(h+2)-1

We replace h=3

3*3 = 2(3+2) - 1

Solve

9 = 2(5)-1

9 = 10 - 1

9 = 9

Is correct h= 3

when we manage to find the same value on both sides of equality it means that the value entered is a possible option

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!

Need help its sector area

Paladinen [302]

Area of sector

$= \frac{30}{360} \times \pi \times {(radius)}^{2}$

$= \frac{30}{360} \times \ \frac{22}{7} \times {(12)}^{2}$

$= \frac{30}{360} \times \ \frac{22}{7} \times 12 \times 12$

so the area = 37.71 square metre
