Find the measure of angle A for both 47 and 48

Step-by-step explanation:

47)25+35x+4x-1=180

24+39x=180

39x=180-24

39x=156

x=4

48)70+9x-5+13x+5=180

70+22x=180

22x=180-70

22x=110

x=5

Hope this helps u...

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the equivalent expression are always the hardest ones but you look at the gcf also
