(2x + 3) + (x+1) + (3x-10) = 180
6x - 6 = 180
6x = 186
x= 31

Answer:
60 & 55
Step-by-step explanation:
1. the sum of the angles 1; 2 and 3 is 180°, then
m∠1=m∠2=m∠3; ⇒m∠3=60°;
2. m∠3=m∠r; ⇒ m∠r=60°;
3. m∠α= 180-(m∠r+65°)°; ⇒ m∠α=55°
all the details are in the picture.
You can just multiply the top and the bottom by the same number, and you will get equivalent fractions.
