Answer» Total MONEY SOPHIA has= $154 Number of boxes = 3 Money she has in each box = $k So total money in the boxes = $3k {3 boxes * money in each box} Remaining money = $4 Equation : 3k+4 = 154 If U wanna find the money in each box as well. Then, 3k+4 = 154 3k= 154-4 3k = 150 k= 150÷ 3 k = $50 Each box has $50.

15.

PLEASE SHOW YOUR WORK!

Answer»

Total MONEY SOPHIA has= $154

Number of boxes = 3

Money she has in each box = $k

So total money in the boxes = $3k {3 boxes * money in each box}

Remaining money = $4

Equation : 3k+4 = 154

If U wanna find the money in each box as well. Then,

3k+4 = 154

3k= 154-4

3k = 150

k= 150÷ 3

k = $50

Each box has $50.

Answer» ANSWER: To find: Height of the HOUSE Tan 15 ° = 0.2679 Tan 5 ° = 0.0875 BC=AD Step-by-step explanation: In triangle ABC, Tan 15 ° = AB/BC 0.2679 = 20/BC BC = 20/0.2679 BC = 74.65 m AC² = AB²+ BC² ( Pythagoras THEOREM ) AC² = 20² + 74.65² AC² = 400 + 5572.6 AC² = 5972.6 In triangle ADE, Tan 5 ° = DE/AD 0.0875 = DE/BC ( AD = BC ) BC * 0.0875 = DE 74.65 * 0.0875 = DE DE = 6.53 m DC² = AC² - AD² DC² = 5972.6 - 5572.6 DC² = 400 DC = 20 m So therefore the height of the house is ED + DC ED + DC = 6.53 m + 20 m EC = 26.53 m ( ED + DC = EC = HEIGHT OF THE HOUSE ) I hope you understood the answer

From a window 20m above the ground, a person could see the top of the house across the street at an angle of elevation of 5 degrees. The angle of depression to the base of the house was 15 degrees. What is the height of the house?

Answer»

ANSWER:

To find: Height of the HOUSE

Tan 15 ° = 0.2679

Tan 5 ° = 0.0875

BC=AD

Step-by-step explanation:

In triangle ABC,

Tan 15 ° = AB/BC

0.2679 = 20/BC

BC = 20/0.2679

BC = 74.65 m

AC² = AB²+ BC² ( Pythagoras THEOREM )

AC² = 20² + 74.65²

AC² = 400 + 5572.6

AC² = 5972.6

In triangle ADE,

Tan 5 ° = DE/AD

0.0875 = DE/BC ( AD = BC )

BC * 0.0875 = DE

74.65 * 0.0875 = DE

DE = 6.53 m

DC² = AC² - AD²

DC² = 5972.6 - 5572.6

DC² = 400

DC = 20 m

So therefore the height of the house is ED + DC

ED + DC = 6.53 m + 20 m

EC = 26.53 m ( ED + DC = EC = HEIGHT OF THE HOUSE )

I hope you understood the answer

ABCD is a trapezoid. PQRS and MLKJ are two rhombusDiagonal of PQRS are 6 cm and 8 cm. One of the angle ofMLKJ is 120 degree and the diagonal bisecting that anglemeasures 15cm. Side of PQRS - AB, side of MLKJ - CDFind XY (median of trapezoid)

Answer»

Answer:

10 cm

Step-by-step explanation:

For rhombus ABCd

Side of ABCD = 12 62+82−−−−−−√ = 12 36+64−−−−−−√

= 12 100−−−√ = 102 = 5cm

For rhombus PQRS,

Here, PQR = 120°

PQO = 60°

POQ = 90°

(DIAGNOALS bisect each other at 90°)

OPQ = 180° - (60° + 90°) = 30°

SQ = 15cm

OQ = 152 = 7.5cm

(diagonals of rhombus bisect each other)

SIN 30° = OQpQ

12 = 7.5PQ => PQ = 15 cm

Side of rhombus PQRS = 15 cm

Now, ML = 5cm, JK = 15 cm

So median = 5+152 = 10 cm

49.

Divide Rs.11000 among A, B and C such that A: B is 33:20 and A: C is 11:19.Find A`s share.

Answer»

Answer:

₹3300

Step-by-step explanation:

$\frac{a}{b} = \frac{33}{20} = \frac{11}{ \frac{20}{3} }$

$\frac{a}{c} = \frac{11}{19}$

THEREFORE A's SHARE is 11x

B's share is 20x/3

and C's share is 19x

Now we can WRITE

$<klux>11X</klux> + \frac{20}{3} x + 19x = 11000$

$33x + 20x + 57x = 33000$

$110x = 33000$

$x = 300$

Hence A's share is 11x= ₹3300
