Question

What is the measure of

∠
x
∠xstart color #11accd, angle, x, end color #11accd?
Angles are not necessarily drawn to scale.

Answer 1

65 degrees
123 angle on the other side it would be 180-123=57 a triangle has 180 degrees add the two angles up minus it from 180 and you get 65

Answer 2

• 
  `\sf \angle x=65^o`

Explanation:

Angles DAB and BAC are supplementary angles because they form a straight line, meaning they add up to 180°.

`\sf \angle DAB+\angle BAC = 180^o`

`\sf 123^o+\angle BAC=180^o`

`\boxed{\sf \angle BAC= 57^o}`

Interior angles of a triangle always add up to 180°:-

`\sf \angle ABC +\angle BAC+\angle x= 180^o`

`\sf 58^o+57^o+\angle x=180^o`

`\boxed{ \sf \angle x=65^o}`
