Sin(A-B) = sinAcosB - cosAsinB
=<span>sin23cos27- cos23sin27</span>
= sin(23-27)
= sin(-4)
=-sin4
To find this answer I can use inverse equations. First subtract 6 from 34, which is 28. Then, divide 28 by 4 and you get 7. x = 7
Answer:
x=10.7, y=11300
Step-by-step explanation:
x%of 31 = 3.317
x/100×31=3.317
31x/100=3.317
31x= 3.317×100
x= 3.317 ×100/31
x =10.7
4407= 39% of y
4407= 39/100 × y
4407 =39y/100
4407×100=39y
4407 × 100/39=y
11300=y

Solution:
<u>Step-1: Find the area of the pizza.</u>
- Area of pizza = πr²
- => πr² = π x 9 x 9
- => 81π = Area of pizza
<u>Step-2: Find the area of the slice.</u>
- = 81π/6 = Area of slice
- => 27π/2 = 13.5π = Area of slice
Option D is correct.
