Does anyone know how to this if so plz help

<1 = 84

<2 = 6

Step-by-step explanation:

The box in the corner of the angle means that it is a right angle which is 90 degrees

<1 + <2 = 90

6x+ x-8 = 90

Combine like terms

7x-8 = 90

7x-8+8 = 90+8

7x = 98

Divide by 7

7x/7 = 98/7

x = 14

<1 = 6x = 6*14 =84

<2 = x-8 = 14-8 = 6

96 39 cause 135 -96=39 im smart (i used a calculater)

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
