Answer:

14) 21.136505024965 m

15) 43.076759215619 km

Step-by-step explanation:

14)

let h be the height of the lighthouse:

tan(41.3) = 18.7/h

Then

h = 18.7÷tan(41.5)

= 21.136505024965 m

………………………………………

15)

90-71.4 =18.6

Let s be the distance that the plane flew

towards the south:

tan(90 - 71.4) = s/128

Then

tan(18.6) = s/128

Then

s = tan(18.6)×128

= 43.076759215619 km

Gre4nikov [31]

Answer:

a) The floor of the room, each edge and the top of the table.

b) The edge of one side and one leg of the table.

c) The angle formed between the sides of the table and the angle between the legs of the table and its edges.

d) The vertices of the top of the table.

e) These are same lines.

Step-by-step explanation:

An angle is the amplitude between the two lines. Plane is an object which consists of two dimensions and infinite points. The segment is a fragmented line. A ray is a line which a starting point and a direction.

Please solve these equations much appreciated

Reptile [31]

Answer:

Part c) $V=16,500\ m^3$

Part d) $V=93,312\pi\ mm^3$ or $V=292,999.68\ mm^3$

Step-by-step explanation:

Part c) Find the volume of the inverted rectangular pyramid

The volume of the rectangular pyramid is equal to

$V=\frac{1}{3}Bh$

where

B is the area of the rectangular base

h is the height of pyramid

Find the area of the base B

$B=(60)(15)=900\ m^2$

$h=55\ m$

substitute

$V=\frac{1}{3}(900)(55)$

$V=16,500\ m^3$

Part d) Find the maximum volume of tea in the tea cup

we know that

The volume of cylinder (tea cup) is equal to

$V=\pi r^{2}h$

we have

$r=36\ mm\\h=72\ mm$

substitute

$V=\pi (36)^{2}(72)$

$V=93,312\pi\ mm^3$ -----> exact value

Find the approximate value

assume

$\pi =3.14$

$V=93,312(3.14)=292,999.68\ mm^3$

An inscribed angle that opens to a diameter has an intersected arc that is a ________________. The angle is a ______ angle becau

kherson [118]

Answer:

An inscribed angle that opens to a diameter has an intersected arc that is 180 degrees. The inscribed angle is a right angle (90 degrees) because

$\frac{1}{2}(180^o)=90^o$

Step-by-step explanation:

we know that

The inscribed angle is half that of the arc comprising

Remember that

The diameter divide the circle into two equal parts

so

An inscribed angle that opens to a diameter has an intersected arc that is 180 degrees

The inscribed angle is 90 degrees because

$\frac{1}{2}(180^o)=90^o$

therefore

An inscribed angle that opens to a diameter has an intersected arc that is 180 degrees. The inscribed angle is a right angle (90 degrees) because

$\frac{1}{2}(180^o)=90^o$
