Answer:
13.7 cm
Step-by-step explanation:
- there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
- since we know that 360°-260.4°=99.6°
- The angle measure of arc AD is 99.6°
Now that we covered that, we can use the arc length formula in order to find the length of arc AD.
- arc length = 2πr(Θ/360°)
- 2π(7.9)(99.6°/360°) = 13.7329
- rounded to the nearest tenth = 13.7
59.99(1.08)= 64.7892
64.7892 rounded to the nearest cent= $64.79
The answer is $64.79.
Hope this helps!
Answer:
2q+6
Step-by-step explanation:
So basically, you would do this.
-2q-6+6q+12-2q
Next
-4q+6q = 2q
12-6=6
2q+6
So a line is 180 degrees. These angles would equal 180. So 180= w + (3w -28). You add 28 too 180, getting 208. Then divide by the 4w. Leading you to w= 52. Plug into the equations to make sure everything checks out
The addition of a negative is basically the same as subtraction.
Since your adding -35 to 90, your just taking away 35 from 90.
You would set up the problem like this:
90 + – 35
Or you could write it out like this:
90 – 35
Either way, 90 + – 35 = 55
