Answer:
Step-by-step explanation:
1.Two adjacent angles : (i) ∠LTN & ∠NTE (ii)∠NTE & ∠STE
2. Acute vertical angles (i) ∠LTN & ∠RTS
3. (i) ∠RTS & ∠STE (ii)∠RTL & ∠LTE
4. ∠STE
5) ∠RNT & ∠SNU
6) ∠RNV & ∠RNS (ii) ∠∠RNV & ∠VNT
7) ∠SNU
8) One angle = x
It's complimentary angle = 90 -x
x - (90 -x ) = 18
x - 90 + x = 18
2x - 90 = 18
2x = 18 + 90
2x = 108
x =108/2
x = 54
The angles are 54 , 36
1. x + 5x = 90 { NR ⊥ MQ)
6x = 90
x = 90/6
x = 15
9y + 18 = 90 { NR ⊥ MQ}
9y = 90 - 18
9y = 72
y = 72/9
y = 8
2. ∠MSN = 90
