Answer: 1/6
Step-by-step explanation:
Because there's only one number that's greater than 5 on a numbered cube and that's '6'
Remember (Soh) (Cah) (Toa). CSC is just the inverse of sine.
Answer:
see explanation
Step-by-step explanation:
The perimeter (P) is the length of all 3 sides of the triangle
The triangle is isosceles with 2 equal sides 20 - 7xy
P = 20 - 7xy + 20 - 7xy + 12 = 52 - 14xy
When x = 2, y = 1, then
P = 52 - 14(2)(1) = 52 - 28 = 24
Answer:
2
Step-by-step explanation:
Answer:
- EF = 4.1
- DE = 9.1
- m∠F = 66°
Step-by-step explanation:
The hypotenuse and one acute angle are given. The relevant relations are ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
__
For the given triangle, these tell us ...
sin(24°) = EF/DF = EF/10
EF = 10·sin(24°) ≈ 4.1
and ...
cos(24°) = DE/DF = DE/10
DE = 10·cos(24°) ≈ 9.1
The remaining acute angle is the complement of the given one:
F = 90° -D = 90° -24°
∠F = 66°
