1) m∠1 = 360°/8 = 45° . . . . . a regular octagon is 8-way rotationally symmetrical, so each sector is 1/8 of a circle.
2) m∠2 = (180° -45°)/2 = 67.5° . . . . . . the angles of a triangle add to 180°. The base angles of an isosceles triangle are equal.
I believe for the first part x would equal -2 and y would equal -1
hope this helps!
Answer:
equation
Step-by-step explanation:
Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry. Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on.

Answer:
5 boys to 9 girls
Step-by-step explanation:
Let x = the number of boys
Boys = x
Girls = x + 4
x + (x + 4) = 14
2x + 4 = 14
2x = 10
x = 5
This means that there are 5 boys. Since girls = x + 4, 5 + 4 = 9. There are 5 boys and 9 girls.
