Answer:
x=5
Step-by-step explanation:
The right angle opposite is the hypotenuse
The 30° is the opposite
SohCahToa
Soh = Sin because you got Opposite and Hypotenuse (because you're trying to find the side, you'd do the opposite of dividing, which is times)
10×sin(30)=5
Answer: x1 = 5
x2 = 1
Step-by-step explanation:
1. Identify the coefficients
2. Move the constant to the right side of the equation and combine
3. Complete the square
4. Solve for x
Answer:
62.8
Step-by-step explanation:
Using the circumference formula (πd) we can see that the answer is 20π, or 62.8
Answer:
![x\leq 76](https://tex.z-dn.net/?f=x%5Cleq%2076)
Step-by-step explanation:
Let x = unknown number
![\implies \dfrac89 \times (x-4)\leq 64](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac89%20%5Ctimes%20%28x-4%29%5Cleq%2064)
![\implies \dfrac{8(x-4)}{9}\leq 64](https://tex.z-dn.net/?f=%5Cimplies%20%5Cdfrac%7B8%28x-4%29%7D%7B9%7D%5Cleq%2064)
Multiply both sides by 9:
![\implies 8(x-4)\leq 576](https://tex.z-dn.net/?f=%5Cimplies%208%28x-4%29%5Cleq%20576)
Expand brackets:
![\implies 8x-32\leq 576](https://tex.z-dn.net/?f=%5Cimplies%208x-32%5Cleq%20576)
Add 32 to both sides:
![\implies 8x\leq 608](https://tex.z-dn.net/?f=%5Cimplies%208x%5Cleq%20608)
Divide both sides by 8:
![\implies x\leq 76](https://tex.z-dn.net/?f=%5Cimplies%20x%5Cleq%2076)
