Answer:

Area of the base is 10.5 cm².

Step-by-step explanation:

Formula for the volume of the given oblique prism = Area of the triangular base × Vertical height between two triangular bases

Vertical height = 6 cm

Volume = 63 cm³

From the formula,

63 = Area of the triangular base × 6

Area of the base = $\frac{63}{6}$

= 10.5 cm²

Therefore, area of the base is 10.5 cm².

timofeeve [1]

Answer:

$x=23.82^o$

Step-by-step explanation:

$Solve ~for~x, first ~ we~ need ~ to ~know~y$

$tan~36=\frac{225}{y}$

$y=\frac{225}{tan ~36}$

$y=309.6859321$

$tan(x)=\frac{225}{y+200}$

$x=tan^{-1}(\frac{225}{309.6858321}$

$x=23.81898048$

$x=23.82^o$

Answer:

B. 72°

Step-by-step explanation:

Remember : Measure of inscribed angle = 1/2 × measure of intercepted arc.

Then

The measure of arc CD = 2 × m∠DBC

= 2 × 36

= 72°

A campsite is 12.88 miles from a point directly below Mt. Adams. If the angle of elevation is 15.5° from the camp to the top of

nata0808 [166]

Answer:

3.57 miles

Step-by-step explanation:

Please consider the attachment.

We have been given that a campsite is 12.88 miles from a point directly below Mt. Adams. The angle of elevation is 15.5° from the camp to the top of the mountain. We are asked to find the height of the mountain.

We can see from the attachment that h is opposite side to angle 15.5 degrees and 12.88 miles in adjacent side.

We know that tangent relates opposite side of right triangle with its adjacent side.

$\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}$

$\text{tan}(15.5^{\circ})=\frac{h}{12.88}$

$\text{tan}(15.5^{\circ})\cdot(12.88)=\frac{h}{12.88}\cdot(12.88)$

$12.88\cdot\text{tan}(15.5^{\circ})=h$

$h=12.88\cdot\text{tan}(15.5^{\circ})$

$h=12.88\cdot(0.27732454406)$

$h=3.5719401274928$

$h\approx 3.57$

Therefore, the mountain is approximately 3.57 miles high.
