Help me pls I need this

1. x = 108°
2. Isosceles triangle
3. Scalene triangle

Explanation:

The sum of all the three angles in a triangle is 180°.

For question 1,
x + 30° + 42° = 180°

x + 72° = 180°

x = 108°

For question 2,
The triangle shown is an isosceles triangle because the both 2 angles are equal to each to other.

For question 3,
The triangle shown is a scalene triangle. Because all the angles are different from one another.

Hope it helps! Mark me brainliest if it’s correct!
