the circle has a diameter of 12, thus its radius is half that, or 6.
As shown in the image, we have a 30 degree angle and x, which is what we want. By doing tan30, we can find x, so tan30=x/70 and 70*tan30=x= 70*sqrt(3)/3. 120-x=height of first tower = 120-(70*sqrt(3)/3) = roughly 79.59
Answer:
Step-by-step explanation:
If you want to solve this easily, you can just remove x and add 30x + 60x.
We know that 30 + 60 is 90. So we will add x to 90.
Now you have your answer!
Hope this helps!
The answer is: 1.25
Remember: Keep the first fraction, Change the Sign, Flip the second fraction.
KEEP - 5/28
CHANGE - division to multiplication
FLIP - 7/1
