what is $mangle1$?\n$mangle1=square^{circ}$
Answer
Explanation:
Step1: Apply the exterior angle theorem
The exterior angle theorem states that an exterior angle of a triangle is equal to the sum of the two non - adjacent interior angles.
Step2: Calculate (m\angle1)
(m\angle1=104^{\circ}+41^{\circ}) (m\angle1 = 145^{\circ})
Answer:
(145)
