Answer:
Step-by-step explanation:
1) <B=122 REASON - 58 AND <B FORMS A LINEAR PAIR SO <B =180-58=122
2) <B=<T REASON VERTICALLY OPPOSITE ANGLES SO <T=122
3) <T AND <D ARE CO-INTERIOR ANGLES SO <D = 180-122=58
4) <T=<Y REASON CORRESPONDING ANGLES SO <Y=58
5) <I =<R REASON VERTICALLY OPPOSITE ANGLES SO <R =58
6) <H=<Y REASON VERTICALLY OPPOSITE ANGLES SO <H=58
7) <A=<D REASON VERTICALLY OPPOSITE ANGLES SO <A =58
8) <I+<A = 58+58= 116
