Answer:
42°(C)
Step-by-step explanation:
That is a right angle which means the sum of angles is 90°
So,we have x+48°=90°
x=90°-48°
x=42°
Answer:
Step-by-step explanation:
Exterior angle = 360/n
= 360/13
= 27.7°
Answer:
I can't see anything what's the question?
Let be the smaller integer. The larger integer is then , and we have
We omit , since is negative.
Then for we find , but this is not odd.
There are no consecutive odd integers that satisfy the given condition!
Answer:
see explanation
Step-by-step explanation:
Using the identity
sin²A = 1 - cos²A , tanA =
Consider the left side
tan²A - sin²A
= - sin²A
=
=
= sin²A ×
= sin²A . tan²A
= right side , thus verified
