Answer:

C 109

Step-by-step explanation:

First add all the known angles inside the triangle first to get 109°

Then since all angles in a triangle add to 180°

you take away 109 from 180 so

180-109 which equals 71

Then since all angles on a straight line add up to 180°

you take 71 from 180 so

180-71 = 109

so x = 109°

NEED THE ANSWER ASAP PLEASE
frutty [35]

Answer:

x = 9

Step-by-step explanation:

Since the angle is bisected by rhe segment then the ratio of the sides to the corresponding parts of the base are equal, that is

\frac{15}{x} = \frac{20}{12} ( cross- multiply )

20x = 180 ( divide both sides by 20 )

x = 9
