Answer:
C
Step-by-step explanation:
The angle adjacent to x on XY = 115° ( corresponding angle )
This angle and x are adjacent and supplementary , thus
x = 180 - 115 = 65 → C

Complete Question:
Which of the following statements is not true?
Choose the incorrect statement below.
Answer:
B. A system of linear equations in two variables must have at least one solution.
Step-by-step explanation:
A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and its slope is always constant.
Similarly, a linear equation is an algebraic equation of the first order with two variables and each of its term having an exponent of one.
Generally, a system of linear equations in two variables must have at least two solution.
For example, y = 2x + 1 is a linear equation.
a. To find the value of y;
When x = 0
y = 2(0) + 1
y = 2 + 1
y = 3
b. To find the value of x;
When y = 0
0 = 2x + 1
2x = -1
x = -½

Step-by-step explanation:
C
Answer:
the answer is a. 147
Explaination:
A triangle always has a sum of 180°.
We already have the angle of two sides give.
10° and 23°
To find the last missing side, you add 10° and 23°, and minus the result from 180°.
10+23= 33
180-33 = 147
