Set up your problem like this x/500 and 70/100. 500 x 70 / 100= 350 350 millimeters would be your answer
Answer:
The value of x= 7 and that of Angle A= 157°
Step-by-step explanation:
(x+16)° = (4x-5)° [Vertically opposite angles]
3x= 21
x= 7
Now, A + (4x-5)° = 180° [Linear pair]
A + [4(7)-5] = 180°
A + 23 = 180°
A = 180° - 23
A = 157°
Hope it helps you
Make each known side into a ratio like so...
75/6
(Because 75 is the shadow casted by the building, and 6 is the shadow casted by sarah)
and 50/x
(50 is how tall the building is and sarah's height is what needs to be found)
Therefore,
75 50
---- -----
6 x
Do cross products;
50 x 6 = 75 x X
300 = 75x
Divide by 75
x = 4ft
