The angle looking up at the sun is 70°. A flagpole casts a shadow of 15 ft. Draw a diagram and find the height of the flagpole
deff fn [24]

Answer:

The length of the flagpole be 41.2 ft .

Option (A) is correct .

Step-by-step explanation:

As given

The angle looking up at the sun is 70°.

A flagpole casts a shadow of 15 ft .

Now by using the trignometric identity .

tan \theta = \frac{Perpendicular}{Base}

\ theta = 70^{\circ}

tan\ 70^{\circ} = \frac{AB}{BC}

BC = 15 ft

tan 70° = 2.75 (Approx)

2.75 = \frac{AB}{15}

AB = 2.75 × 15

     = 41.2 ft

Therefore the length of the flagpole be 41.2 ft .

Option (A) is correct .

Write a vector equation of the line that passes through P(4, 7) and is parallel to a = (3, 8).
Anvisha [2.4K]

Answer:

B

Step-by-step explanation:

(x,y) = P + (a)t

(x,y) = (4,7) + t(3,8)

(x,y) - (4,7) = t(3,8)

(x-4, y-7) = t(3,8)

Sarawongs school is selling tickets to the anual talent show on the first day of ticket sales the school sold 1 adult ticket and
vaieri [72.5K]

Price of one adult ticket is $9 and price of one student ticket is also $9.

Step-by-step explanation:

Let,

Adult ticket = x

Student ticket = y

According to given statement;

x+2y=27   Eqn 1

2x+2y=36   Eqn 2

Subtracting Eqn 1 from Eqn 2;

(2x+2y)-(x+2y)=36-27\\2x+2y-x-2y=9\\x=9

Putting x=9 in Eqn 1;

9+2y=27\\2y=27-9\\2y=18

Dividing both sides by 2;

\frac{2y}{2}=\frac{18}{2}\\y=9

Price of one adult ticket is $9 and price of one student ticket is also $9.
