Answer:
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
Step-by-step explanation:
We are given that
Exterior angle=
We have to find the value of x.
We know that
Exterior angle=Sum of opposite interior angles of triangle
Using the property
Subtract 85 from both sides we get
Option B is true.
B. x = 62 because 147 – 85 = 62 and 85 + 62 = 147
Option B:
ASA congruence
Solution:
Step 1: Given
Step 2: Given
Step 3: Given
(Included side)
Step 4: All right angles are congruent.
(Angle)
Step 5: By vertical angle theorem
(Angle)
Step 6: By ASA congruence
QU and RU are included side of corresponding angles.
Therefore by ASA congruence rule,
Option B is the correct answer.
Hence proved.
