Question

find the value of x please .

Answer 1

Answer:

21 is the correct answer

180°(sum of the angles in a triangle)-40°=140°

if x is 21°, 5x+14° would be 119°

119°+21°=140°

Answer 2

Answer:

The correct answer is A. 21

Step-by-step explanation:

Let's recall that the interior angles of a triangle  add up to 180°, therefore, we have this equation:

40 + x + 5x + 14 = 180

6x = 180 - 14 - 40

6x = 126

x = 126/6

x = 21

The correct answer is A. 21

The angles of the triangle are: 40°, 21° and 119°
