Sagot :

Answer:

x= 11

Step-by-step explanation:

=> 8x+5x+37 = 180° { angle sum property }

=> 13x +37 = 180°

=> 13x = 180-37

=> 13x = 143

=> x = 143/13

=> x= 11

Answer:

x = 11

Step-by-step explanation:

the sum of the 3 angles in a triangle is 180°

sum the 3 angles and equate to 180

8x + 5x + 37 = 180 , that is

13x + 37 = 180 ( subtract 37 from both sides )

13x = 143 ( divide both sides by 13 )

x = 11
