Answer:
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent. ASA
Step-by-step explanation:
Answer:
1. X= 56
2. X= -11/2 (When you solve you get this if you need it as a mixed number it's X= -5 1/2
Step-by-step explanation:
simplifying means: Reducing to lowest terms.
To solve for x simplify both sides of the equation, then isolate the variable.
Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126
so, Angle B is 126 degrees
I hope that helps!
