Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from angle I, we know the opposite side and the hypotenuse. Therefore, we should use sine.
sin(I) = 
To solve, you can use your calculator and the inverse sine function (sin^-1).
I = sin^-1()
I = 61 degrees

Answer:
86.9 km/h
Step-by-step explanation:
54 mph = 86.9046
Full number: 86.9046 km/h
The map scale is 6 in : 36 mi
simplify it, divide 6 from both sides
6/6 = 1
36/6 = 6
1 in : 6 mi
To find the amount of inches in 52 miles, divide 52 with 6
52/6 = 8.67 (rounded)
8.67 in should be your answer
hope this helps
Answer:
-2i+8
Step-by-step explanation:
(1+i)(3-5i)
3+3i-5i-5i^2
3-2i-5(-1), because i^2=-1,
3-2i+5
-2i+3+5
-2i+8
