According to angles sum property
∠A + ∠B + ∠C =180°
given,
∠A =1°
∠B =1°
so,
∠C =180-2 °
=178°
so, ∠C =178 °
The third angle =178 °
∠A + ∠B + ∠C =180°
given,
∠A =1°
∠B =1°
so,
∠C =180-2 °
=178°
so, ∠C =178 °
The third angle =178 °

According to angle sum property
A + B + C= 180---------1
A = 1
B = 1
Subs in equation 1
1+1+ C=180
2+C=180
C=180-2
C=178
Therefore the third angle is 178
A + B + C= 180---------1
A = 1
B = 1
Subs in equation 1
1+1+ C=180
2+C=180
C=180-2
C=178
Therefore the third angle is 178
