Answer:
Corresponding angles
Alternate interior angles
Alternate exterior angles
Vertical angles
Step-by-step explanation:
Answer:
1: 36° 2: 122° 3: 122° 4: 38°
Step-by-step explanation:
First start out by getting 2 and 3. so 58+angle 3 has to sum to 180° since they are supplementary and are a straight line. So 180-58=122. Angle 2 is the same since theyre vertical. then since a triangle has 180° total, you subtract from 180 to find the final angle measurement.
Answer:
i think it's B, I'm not 100% sure
X = y - 3 (equation 1)
2x + y = 12 (equation 2)
Substitute equation 1 into equation 2, replacing every x value with equation 1
2(y - 3) + y = 12
Now, distribute the 2 inside the brackets and simplify.
2y - 6 + y = 12
3y = 18
y = 6 (divided both sides by 3)
Substitute y back into equation 1 to find x.
x = 6 - 3
x = 3
Verify that these are correct by substituting them into equation 2.
2(3) + 6 = 6 + 6 = 12
Therefore, x = 3 and y = 6
