Answer 1

Answer:

4.

y+105=180°

180-105=75°

y=75°

sum of triangle is always 180°

SO

55+75+x=180°

130+x=180°

x=180-130=50°

x=50°

=======================================================================

2.

let the number = x

6times means 6x

now if we subtract 5 from this

then you will get 7

(6x-5 = 7)

now

to find x value

6x=7+5

6x= 12

x= 12/6

X=2

the number is 2.
