Answer:

m∠STM = (3x + 11)

Since there is only one given equation, which is 3x + 11,

Assuming triangle TSM is an equilateral triangle from triangle STM

m∠STM = (3x + 11)

m∠STM = 3(49/3) + 11

m∠STM = 49 +11

m∠STM = 60°

m∠MTA = m∠STM/2

m∠MTA = 60/2

m∠MTA = 30°

m∠TSA = 60 + 60

m∠TSA = 120°

m∠TSM = m∠TSA /2

m∠TSM = 120/2

m∠TSM = 60°

1. m∠MTA = 30°

2. m∠TSM = 60°
