This is a proportion problem. Let the monument me x feet tall.
40/x=5/6
Cross multiply:
240=5x
x=48 ft.
So the monument is 48 ft tall,

Answer:

48\ ft

Step-by-step explanation:

we know that

Adam is 6 feet tall and casts a 5-foot shadow

A monument casts a 40-foot shadow

so

by proportion

Find how tall is the monument

Let

x------> the height of the monument

\frac{6}{5}=\frac{x}{40}\\ \\ x=40*6/5\\\\x=48\ ft

P, Q &amp; R form a right-angled triangle.
kvasek [131]

Answer:

∠RPQ = 27

Step-by-step explanation:

In ΔSRQ,

∠R = 90

∠SQR = 36°

∠R + ∠SQR + ∠RSQ = 180    {Angle sum property of triangle}

90 + 36 + ∠RSQ = 180

126 + ∠RSQ = 180

         ∠RSQ = 180 - 126

        ∠RSQ = 54°

∠PSQ +∠RSQ = 180   {Linear pair}

∠PSQ + 54 = 180

 ∠PSQ = 180 - 54

∠PSQ = 126

In ΔPSQ,

SQ = PS ,

So, ∠SQP = ∠SPQ    {Angles opposite to equal sides are equal}

∠SQP = ∠SPQ   =x

∠PSQ + x +x = 180  {Angle sum property of triangle}

126 + 2x = 180

2x = 180 - 126

2x = 54

x = 54/2

x = 27

∠RPQ = 27°

Reba measured a house and its lot and made a scale drawing. She used the scale 9 inches = 7 feet. What is the scale factor of th
Otrada [13]

The scale factor of the Reba's drawing is 9/84, 3/28

Step-by-step explanation:

The scale factor is the ratio between the two corresponding sides of the figure. The point worth noting in computing the scale factor is that both sides must have similar units of dimension while using for comparison purpose.

Given the scale used by Reba is 9 inches to 7 feet

Since both the units are different, we have the option to either convert inches to feet or vice versa

We proceed with converting feet to inches

We know that 1 foot equals to 12 inches. Hence 7 feet would equal 84 inches.

Now scale factor= first dimension/ corresponding dimension

Scale factor= 9/84 which can be reduced to 3/28
