Question

if y =73°find the value of x
if x = 14° find the value of y​

Answer 1

Step-by-step explanation:

we know that the total angle is 180 degrees

so,5x+(2y-16)=180

1) given y=73 degrees

5x+(2×73-16)=180

5x+146-16=180

5x+130=180

5x=180-130

5x=150

x=150/5

x=39

2) given x=14 degrees

5×14+2y-16=180

70+2y-16=180

54+2y=180

2y=180-54

2y=126

y=126/2

y=63
