Answer:
cos(55) = 11/x
Step-by-step explanation:
We have the hypotenuse (x) and an angle adjacent to 55 (11). The only trigonometric formula that uses adjacent and hypotenuse is cosine (adjacent/hypotenuse), so that will be your answer.
Answer:
see explanation
Step-by-step explanation:
Given
x + 
≤ - 3 or x - 3 > - 2
Solve the left and right inequalities separately, that is
x + ≤ - 3 ( isolate x by subtracting from both sides )
x ≤ - 3 - , that is
x ≤ - 
- , thus
x ≤ - 
OR
x - 3 > - 2 ( isolate x by adding 3 to both sides )
x > 1
Solution is
x ≤ - or x > 1
74,233 increased by 58,490 is 74,233 * 58,490 so its 4,341,888, 170. So 4 billion, 341 million, 888 thousand, 170.
Scientific notation is 4.34188817 * 10 to the 9th power.
