Two parallel lines are crossed by a transversal.

horizontal and parallel lines b and c are cut by transversal a. at the intersection of lines b and a, the bottom left angle is (5 x + 5) degrees. at the intersection of lines c and a, the bottom right angle is 115 degrees.
what is the value of x?

Step-by-step explanation:

b//c;  a is transversal

5x + 5 + 115 = 180    { 5x+5 and 115 are supplementary angles}

5x + 120 = 180

5x = 180 -120

5x = 60

x = 60/5

x =12

a framing bias

step-by-step explanation:

rodrigo is subject to a framing bias i believe.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
