Answer:
see explanation
Step-by-step explanation:
and 
cannot be simplified as they are already in simplest form.
Note that + ≠ 
Thus
2 + 5 ← cannot be simplified any further
Answer:
c. 40°
Step-by-step explanation:
The information given has been illustrated in the figure drawn in the attachment below.
m<BAD = 50° (angle bisector theorem)
m<ADB = 90° (perpendicular bisector)
m<ABD = 180 - (m<BAD + m<ADB) (sum of angles in a triangle)
m<ABD = 180° - (90° + 50°)
= 180° - 140°
= 40°
B = 40°
The second equation is y=5x+2
0.05 = 5% = 5/100
Simplify 5/100 and you get 1/20.
Hope this helps & good luck. :)
