Answer is in the pic above. Theorems used:
Exterior angle theorem
Inscribed angle theorem.

Answer:
a=34 °
b=76°
c=70°
d=70°
Step-by-step explanation:
The angles 76° , 34°, and c make up a triangle. A triangle has a sum of 180°.
180° = 76° + 34° +c
c=70°
The parallel lines create 2 congruent triangles so we can use the same angles from the first triangle for the second one.
Answer:
B) No, they are not congruent.
Step-by-step explanation:
Answer:
I = V/R
Step-by-step explanation:
V = IR
Divide by R on both the sides,
I = V/R
