To measure a stone face carved on the side of a mountain, two sightings 750 feet from the base of the mountain are taken. if th

Sergeeva-Olga [200]

Answer: 57.8512 feet (approx)

Step-by-step explanation:

Let h be the height of the stone face.

The angle of elevation from one sight to the bottom of face that is 750 feet far from the base of the mountain is 33°

⇒ The distance of the base of the stone face from the base of the mountain = $750\times tan 33^{\circ}=750\times 0.64940759319=487.055694898$

The angle of elevation from another sight to the top of face is 36° that is also 750 feet away from the base of the mountain,

Therefore,

The distance of the top of the stone face from the base of the mountain = (h + 487.055694898) feet

By the trigonometry,

$\frac{h + 487.055694898}{750}=tan36^{\circ}$

$h + 487.055694898=0.726542528\times 750$

$h =544.906896004-487.055694898=57.8512011059\approx 57.8512$

Therefore, the height of the stone face is 57.8512 feet (approx).

Gnoma [55]

Answer:

Its a parallelogram

Step-by-step explanation:

Since there are 4 points we know it has to be a 4 sided shape. Since 3 out of the four sides are equal, then we know that this shape has to be a parallelogram so it has at least one pair of parallel lines.

50 POINTS <br> HELP DUE IN 30 MINS!!!

LUCKY_DIMON [66]

$4 < 5 < 9$

$2^2 < 5 < 3^2$

$2 < \sqrt 5 < 3$

$-3 < -\sqrt 5 < -2 < -1.96312...$

$-\sqrt 5 < -1.96312...$

10.

The least will be one of the negative ones, -3 or -6/5. Since -6/5=-1.2, we see

-3 is the least

11.

81 < 90 < 100

$9^2 < 90 < 10^2$

$9 < \sqrt{90} < 10$

Answer: 10 feet

12.

We know $\sqrt 8 > \sqrt 5$ and $2.5 > 2 \frac 1 3$

Since

$2.5^2 = 6.25 < 8$

$\sqrt 8$ is the tallest.

Rosa and her brother worked landscaping jobs last summer. Rosa earned $8 more than twice the amount earned by her brother. If th

nadezda [96]

Rosa earned $50

Explanation:

Two people Rosa & her brother
Her brother earns X
While Rosa earns 2X + 8
Now we gotta solve for X

They made $71. $71 minus X should give you Rosa’s pay

71 - X = 8 + 2X (subtract 8 from 71)
63 - X = 2X (add X to 2X)
63 = 3X (divide by 3)
21 = X

Plug in $21 for Rosa:
8 + 2(21)
8 + 42 = $50
