Answer:
MATHS
Step-by-step explanation:
1. 180° in a triangle
2. 60° in each angle
3. you can use Pythagoras theorem
* Equation = A² + B² = C²
42.74 m²
full circle area = πr² = (3.14)(7²) = 153.86 m²
(100°/360°)(153.86 m²) = 42.74 m²
We know that the factors of the number 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.
so it would be 1,2,3,5,6,9 hope it helps :)
You multiply all the numbers by 2 to get rid of the fractions. This would leave you with k + 1 = 6. Then you subtract 1 from both sides to get k = 5.
