Sagot :
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!
