3:7, Basically simplifying it.
Answer: 6x+9c+4
Step-by-step explanation: (8 + 6x) + (-4 + 9c)
8+6x-4+9c
6x+9c+8-4
6x+9c+4
Should be A if I’m not mistaken
Answer:
The computation of the angles show that the value of sin x and cos y will be 4/5 and 3/5 respectively.
How to calculate the angles?
From the information, we've to compute the length of the hypothenuse using Pythagoras theorem.
Therefore, 4² + 3² = hypothenuse²
hypothenuse² = 16 + 9
hypothenuse² = 25
hypothenuse = ✓25.
hypothenuse = 5
Therefore, sin x = opposite/hypothenuse = 4/5
cos y = adjacent/hypothenuse = 3/5
In conclusion, the values are 4/5 and 3/5.
Step-by-step explanation:
