-22 is one integer. As the definition of integers, that a set of whole numbers and their opposites. -22 can not be a entirety number because it has actually a negative sign, a entirety number can not it is in a fraction, a decimal no one a negative. All entirety number are integers but not every integers are totality numbers.

Circumference, C = 62.8 ft

Area, A = 314 ft²

Step-by-step explanation:

where π = 3.14

Circumference, C = 2π(r)

= 2π(10ft)

= 20π ft

= 62.8 ft

Area, A = π(r²)

= π(10ft)²

= 100π ft²

= 314.1593654 ft²

= 314 ft²

(1) The angles space 81⁰, 76⁰, 23⁰ and also y = 157⁰

(2) The angles room E = 122⁰, p = 40⁰, and Q = 18⁰

Step-by-step explanation:

(1)

Considering the an initial diagram;

(4x + 29) + (5x + 11) + (2x - 3) = 180 (sum of angle in a triangle)

collect prefer terms together;

(4x + 5x + 2x) + ( 29 + 11 - 3) = 180

11x + 37 = 180

11x = 180 - 37

11x = 143

x = 143 / 11

x = 13

The angles of this triangle are calculated as follows;

4x + 29 = (4 x 13) + 29 = 81⁰

5x + 11 = (5 x 13) + 11 = 76⁰

2x - 3 = ( 2 x 13) - 3 = 23⁰

y⁰ + (2x - 3) = 180 (sum of angle on a right line)

y⁰ + 23⁰ = 180

y⁰ = 180 - 23

y = 157⁰

(2)

Considering the 2nd triangle;

(15m + 17) + (7m - 9) + (4m - 10) = 180 (sum of angles in a triangle)

(15m + 7m + 4m) + (17 - 9 - 10) = 180

26m - 2 = 180

26m = 180 + 2

26m = 182

m = 182 / 26

m = 7

The angles of this 2nd triangle are calculated as follows;

E: 15m + 17 = (15 x 7) + 17 = 122⁰

P: 7m - 9 = (7 x 7) - 9 = 40⁰

Q: 4m - 10 = ( 4 x 7) - 10 = 18⁰
