Find m
Pls help

.

48

Step-by-step explanation:

80+3x+14+5x-10=180(sun of angles fo triangle)

8x+4=100

x=12

now for f

3x+14

=3*12+14

=48

m<F = 48

Step-by-step explanation:

180 - 100 = 80

m<G=80

3x+14+5x-10+80

8x + 84 = 180

-84 = -84

8x = 96

8 = 8

x = 12

3(12) +14 = 48

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
