Answer:

x= 69°

Step-by-step explanation:

First find the inner angle of the 159°

so you would do 180-159=21

next you add 21 ° to the 90° from the right angle

that gives you 111°

last you do 180-111 and you get 69

Answer:

x = 69

Step-by-step explanation:

180 - 159 = 21

The sum of the three angles of any triangle is equal to 180 degrees, so:

21 + 90 + x = 180

111 + x = 180

180 - 111 = x

x = 69

Have a nice day!
