#9. There are 180 degrees in a triangle. We already know two of the sides which added together make 112. Then we do, 180-112=68

#10. We do the same process. 90 + 60 = 150
150-180= 30

#11. To find whether or not any three numbers can make a triangle, two of the numbers must equal more than the remaining number. But this has to be the case for any combination. 6+7=13. 13 is larger than 11. So yes it can.

#12. 8+2=10 which may be bigger than 6 but, 6+2=8. Which is equal to 8. So no, it cannot make a triangle.

Given :-

The slope of the line through points (3,y) and (4,10) is 7 .

To Find :-

The value of y .

Solution :-

As we know that the slope of the line is difference of ordinate divided by the difference of absicca as ,

$\longrightarrow$ m = y -10 / 3 - 4

$\longrightarrow$ 7 (-1) = y -10

$\longrightarrow$ -7 = y -10

$\longrightarrow$ y = 10 -7

$\longrightarrow$ y = 3

Hence the required answer is 3.
