Answer:
90°
Step-by-step explanation:
Through point O draw a ray on left side of O which is || to AB & CD and take any point P on it.
Therefore,
∠ABO + ∠BOP = 180° (by interior angle Postulate)
118° + ∠BOP = 180°
∠BOP = 180° - 118°
∠BOP = 62°.... (1)
Since, ∠BOP + ∠POD = ∠BOD
Therefore, 62° + ∠POD = 152°
∠POD = 152° - 62°
∠POD = 90°.....(2)
∠POD + ∠ODC = 180° (by interior angle Postulate)
90° + ∠ODC = 180°
∠ODC = 180° - 90°
Answer:
A)2
Step-by-step explanation:
we would like to integrate the following definite Integral:
use constant integration rule which yields:
notice that we can rewrite √x using Law of exponent therefore we obtain:
once again use law of exponent which yields:
use exponent integration rule which yields;
simplify which yields:
recall fundamental theorem:
simplify:
hence
our answer is A
