Answer:
x= 11
Step-by-step explanation:
4x+5/7 =2x-1/3
multiply both of the equation by 7 first
4x+5/7 times 7 = 2x-1/3 times 7
4x+5= (2x-1)7/3
now multiply 3 to both sides
3(4x+5)= (2x-1)7/3 times 3
3(4x+5)= (2x-1)7
now you should distribute on both sides
(4x times 3)+(5 times 3)= (2x times 7)-( 1 times 7)
12x+15= 14x-7
subtract 12x from both sides
12x-12x+15= 14x-12x-7
15= 2x-7
add 7 to both sides
15+7= 2x-7+7
22= 2x
divided both sides by 2
22/2 = 2x/2
11=x
5x
no because it is not a right angled triangle.
this means angle A is not 90° so AB cant be a tangent.
