Does anyone know how to do this it’s geometry angles . And you have to make an equation if you know this please help.

Step-by-step explanation:

Problem 1)

The given angle is a right angle with measure 90° so

2x + x = 90°

3x = 90°

x = 30°

Problem 2)

The given angle is a straight angle with measure of 180°

2x + 3 + x - 6 = 180° add like terms

3x - 3 = 180°

3x = 183°

x = 61°

Problem 3)

The given angles are corresponding angles with same angle measurement

x + 16 = 4x - 5

21 = 3x

7 = x

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
