Answer:
x = 5√3; y = 5
Step-by-step explanation:
Finding y: The sine function links the 30° angle, the 10 unit hypotenuse and the side opposite the angle, y:
sin 30° = 1/2 = y/10
Solve the equation of ratios
1 y
-- = ----- using cross-multiplication first: 2y = 10 → y = 5
2 10
We can now find x either by using a similar approach and the cosine function or by using the Pythagorean Theorem:
x² + y² = 10² = 100 → x² = 100 - y² = 100 - 5² = 75
If x² = 75, then x = ±√75 = ± (√25)·(√3) → ±5√3
Since lengths are always positive, take x = 5√3 as the answer.
Answer:
3/4
Step-by-step explanation:
Convert the fractions into decimals.
5/8 = 0.625
3/4 = 0.75
0.75 is greater than 0.625.

Answer:
64
Step-by-step explanation:
4^3 is the same as 4x4x4
4x4 = 16
16x4=64
so 4^3 is 64
