Answer: 27 degrees
Step-by-step explanation:
y is 63 degrees because they are alternate interior angles. Then, 90-63=27 which is the answer.
Answer:
x = 25
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
That is ∠ D and ∠ B are corresponding angles and congruent, thus
4x - 20 = 2x + 30 ( subtract 2x from both sides )
2x - 20 = 30 ( add 20 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25
Answer:
0≥6y
Step-by-step explanation:
y-5(y+1)≥2y-5
y-5y-5≥2y-5
-4y≥2y
0≥6y
Answer:
y = -1/2x
Step-by-step explanation:
The slope is negative and 1/2, and y-intercept is 0
