What is the measure of x?

In ΔABC,

angle BAC = 180 - 123 = 57°(Linear pair)

Now, We Know,

Sum of all angles in a triangle = 180°

therefore,

angle BAC + angle BCA + angle ABC = 180°

58 + 57 + x = 180°

115° + x = 180°

x = 180° - 115°

x = 65°...ans

Hope it helps you!!

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
