And because we know that we cut the base of the equilateral triangle in half, we can see that the side opposite the 30° angle (the shortest side) of each of our 30-60-90 triangles is exactly half the length of the hypotenuse.
2800
The math behind it:
800(Mph) x 3(Hours) = 2400(Miles traveled in 3hrs)
800(Mph) x 1/2(or .50hrs) = 400(Miles traveled in 1/2 an hr)
2400(Miles traveled in 3hrs) + 400(Miles traveled in 1/2 an hr) = 2800(Miles traveled in 3 and 1/2hrs)
Hope this helps! :) Have a nice day!
Answer:
= -1/6
Step-by-step explanation:
(7-9) / (18-6)
=-1/6
Answer:
x ≈ 63.6°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan x = 
= 
= 
, thus
X = 
( ) ≈ 63.6° ( to 1 dec. place )
