Answer:

Step-by-step explanation:The simplification
1+1×80+5-23+456×47+56784-2647
=1+80+5−23+(456)(47)+56784−2647
=81+5−23+(456)(47)+56784−2647
=86−23+(456)(47)+56784−2647
=63+(456)(47)+56784−2647
=63+21432+56784−2647
=21495+56784−2647
=78279−2647
=75632
Converting 75632 into standard form

Answer: 20°
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Angle 1 = 55°
Angle 2 = 105°
The sum of the three interior angles of a triangle is always 180°.
So:
180 = 55+105 + x
Where x is the missing angle.
Solving for x:
180-55-105 =x
20°=x
