Answer:
x = 115° , y = 140° , z = 40°
Step-by-step explanation:
40° , x and 25° lie on a straight line and sum to 180° , that is
x + 40° + 25° = 180°
x + 65° = 180° ( subtract 65° from both sides )
x = 115°
z and 40° are vertically opposite angles and are congruent , then
z = 40°
y and z lie on a straight line and sum to 180° , that is
y + 40° = 180° ( subtract 40° from both sides )
y = 140°
Answer:
Step-by-step explanation:
Step 1: Identify the approach:
With this problem, the general solution is to try manipulate given data and transform data into a new form, in which, the desired value is on the left side and all of other components which do not contain
or
are on the right side.
Step 2: Analyze:
Realize that in both equations, the and
are in form of different signs. Then adding up corresponding sides of both equation can help eliminate these undesired components.
Step 3: Perform manipulation:
Rearrange:
Simplify:

Answer:
Possible options:
= -4 * 3 1/4
= -4 * 13/4
= -4 * 3.25
Step-by-step explanation:
Without the options that seemed to go along with this question, it will be difficult to give the exact expression, but here are a few options.
-4 * 3 1/4 = -13
-4 * 13/4 = -13
-4 * 3.25 = -13
Each of these expressions will give the product of -4 and 3 1/4.
