Answer:
100°= angle b(VERTICAL OPPOSITE ANGLE)
100°+x°=180°[co interior angle]
x=180°-100°
x=80°

Answer:

Step-by-step explanation:
To find the slope, rearrange the equation to y=mx+b or y=mx+c.

Subtract 4x from both sides:

Divide 5 on both sides:


In the equation of y=mx+b/y=mx+c, m will be the slope.
Therefore, the slope is 
Answer:
it is SAS
Step-by-step explanation:
because BC is common side in both triangles
so
now two triangles have 2 sides equal and 1 angle equal so
it is congruent by SAS rule
