Question

3x + 21 6x - 60 find the two angles measure from the diagram answers 78,102 78,78 or 102,102​

Answer 1

• 102 and 102

Explanation:

There is no diagram attached

It is assumed the angles are vertical

Vertical angles are congruent as per vertical angles theorem

• 3x + 21 = 6x - 60
• 6x - 3x = 21 + 60
• 3x = 81
• x = 81/3
• x = 27

Angle measures

• 3*27 + 21 =81 + 21 = 102

So the answer is

• 102 and 102
