Question

find the value of x and find the value of the angle with the star in it​

Answer 1

x is equal to 3

u make an equation like this 12x + 34 = 19x + 13
then subtract 13 from both sides of it which gives u 12x + 21 = 19x
then u subtract 12x on both sides, leaving u with 21 = 7x
divide both sides by 7 and u get 3 = x
hope this helps
