Step-by-step explanation:
You solve for x and get x<-2 or x>= -1/2 and then graph
The set is not closed
Example:
-4 * -3 = 12 this is not a negative integer
Answer:
∠A = 45°
Step-by-step explanation:
The sum of angles in a triangle = 180°.
That means in the triangle ABC, ∠A + ∠B + ∠C = 180°.
Given ∠B = 90° and ∠C = 45°.
⇒ ∠A + 90° + 45° = 180°
⇒ ∠A = 180 - 90 - 45
⇒ ∠A = 45° is the required answer.
