Answer:
A
Step-by-step explanation:
The triangles are the same size but in a different form. Y= 50 and a and b equal eachother.
Answer:
2x^2+23.
Step-by-step explanation:
Combine like terms.
This expression simplified is 2x^2+23.
Answer:
x = 52, y = 137 degrees.
Step-by-step explanation:
x = 180 - 90 - 38
x = 52 degrees (as there is 180 degrees in a triangle).
As they are the same side inner angles between 2 parallel lines:
x + (y - 9) = 180
52 + y - 9 = 180
y = 180 - 52 + 9
y = 137 degrees.
Answer:
3 4/5
Step-by-step explanation:
divide 19 by 5 which gets you that as a decimal
