LaTeX: x^2+y^2=r^2 x 2 + y 2 = r 2 x 2 + y 2 = r 2 x 2 + y 2 = r 2

LaTeX: a^2+b^2=c^2 a 2 + b 2 = c 2 a 2 + b 2 = c 2 a 2 + b 2 = c 2

LaTeX: \sin^2\Theta+\cos^2\Theta=1 sin 2 ⁡ Θ + cos 2 ⁡ Θ = 1 sin 2 ⁡ Θ + cos 2 ⁡ Θ = 1 sin 2 ⁡ Θ + cos 2 ⁡ Θ = 1

LaTeX: x^2+y^2=1 x 2 + y 2 = 1 x 2 + y 2 = 1 x 2 + y 2 = 1

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
