Answer: the mistake was not putting the 5 in the perthesis
Step-by-step explanation:
Because 5(x-1 how yu gon make that equal 5x-1 it has to be in the correct way to equal the same thing
6. 150 degrees
7. 70 degrees
8. 100 degrees
Answer:
8 - 
Step-by-step explanation:
For this problem you have to use the 45-45-90 triangle theorem and 30-60-90 theorem.
For 45-45-90, the isosceles sides = 4, so the hypotenuse of the 30-60-90 triangle is 4 times 2, which is 8. If x is 8, then since y is the side across from the 60 angle, y is
. Since this really can't be simplified after y is subtracted from x, the final answer is just 8 -
.
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 2
