Answer:

m∠UVT = 97°

Step-by-step explanation:

Given m∠WVU = 169°, m∠WVT = (2x + 20)° and m∠UVT = (3x + 19)°, according to the diagram shown, it is seen that;

m∠WVU = m∠WVT +m∠UVT

Substitute the given parameters into the function as shown;

(2x + 20)°+(3x + 19)° = 169

collect like terms

2x+3x+20+19 = 169

5x+39 = 169

5x = 169-39

5x = 130

x = 130/5

x = 26°

Since m∠UVT = 3x+19, substitute x = 26 into the function

m∠UVT = 3(26)+ 19

m∠UVT = 78+19

m∠UVT = 97°
