Answer:
5
Step-by-step explanation:
By the pythagorean theorem, x^2 = 13^2-12^2. 13^2-12^2 = 25, and the square root of 25 is 5
Answer:
4^2 / px3 = 2/3
Step-by-step explanation:
4^2 / px3 = 4^2 / 8 *3
= 4*4 / 8*3
= 4/ 2*3
= 2/3
Answer: 18
Step-by-step explanation:
Perimeter of semicircle: 1/2 π × d + d
1/2 π × 12 + 12
π6+ 12
π18
Step-by-step explanation:
The distance from the surfer to the shoreline will be found as follows:
tan θ= opposite/adjacent
θ=10°
opposite=7ft
adjacent= x ft
substituting the values in our formula and solving for x we get
tan 10=7/x
hence
x=7/tan10
x=39.69897~ 39.7 ft
The surfer is 39.7 ft from the shoreline.
