Answer 1

Answer:

NO, It’s not a right triangle

Step-by-step explanation:

Using the converse of Pythagoras’ theorem if the triangle is right then

Square on longest side = sum of square of the other sides

70^2= 4900

55^2 + 42^2 = 4789

Since 4900 ≠ 4789 not a right triangle

Answer 2

No

Step-by-step explanation:

Assuming sides ABC, the values of the angles would be the following.

Angle ∠A = 94.905° = 94°

Angle ∠B = 35.535° = 35°

Angle ∠C = 49.561° = 49°

A right triangle is a triangle with a 90° angle. Therefore, the answer is no.
