Answer 1

Answer:

18×[7+(-3)]=[18×7]+[18×(-3)]

=> 18×4 = 126-54

=> 72 = 72

Answer 2

Step-by-step explanation:

5q).

we know that the sum of opposite interior angles of a triangle is equal to the corresponding external angle.

angles are in ratios 2:3

hence, 2x+3x = 125°

5x=125°

x=125°÷5= 25°

thus. 2x= 25×2= 50°

3x=25×3= 75°

let the other angle is y° then,

2x+3x+y= 180°. (angle sum property)

50°+75°+y°=180°

125°+ y° = 180°

y°= 180°-125° = 65°

Therefore the angles are 50°,75°,65°.
