Step-by-step explanation:
Here apply the relationship of angles formed on a straight line.Angles formed on a straight line add up to 180°
13. m∠1 = 180° - 68° = 112°
14. m∠3=180°-122°=68°
15. m∠4=180°-(68°+90) = 180°-158°=22°
16. m∠5=90° ⇒right-angle
17.
Finding the value of x will require you to equate the sum of the expressions for the two angles to 180°
(2x+11)° + (6x-7)°=180°
2x+6x+11-7=180°
8x+4=180°
8x=180°-4°
8x=176°
x=176°/8 = 22°
Hence ;
∠MHT = (6x-7)°
=(6*22 -7)°
=(132-7)°
=125°
and
∠AHM = (2x+11)°
= (2*22 +11)°
= 44 + 11 = 55°
