They are right triangles so you can use the Pythagorean theorem.
A = sqrt(5^2+3^2)
A = sqrt(25+9)
A = sqrt(34) (exact answer)
As a decimal it would be: 5.8
B = 45 = sqrt( 20^2 + b^2)
B^2 = 45^2-20^2
B^2 = 2025-400
B^2 = 1625
B = sqrt(1625)
B = 5sqrt(65) exact answer
As a decimal : 40.3
Answer:
6 foot
Step-by-step explanation:
so you can make a ratio out of it kinda
height : shadow height
18 : 12
1.5 : 1
so if its height : 4
the height would be 6 (4 + 2)
hope that makes sense :)
Answer:
4cm
Step-by-step explanation:
well 100 degrees is 1.745 radians
s=r Θ
so r=7/1.745=4 cm
