Answer:

1. x=20 ; the angles are 90 degrees31 degrees 59 degrees

2. x=16; the angles are 16 degrees 92 degrees 72 degrees

Step-by-step explanation:

1. 180=90+31+(3x-1)

180-90-31=3x-1

59=3x-1

60=3x

x=20

plug in x for the third angle

2. 180= x+5x-8+3x+44

180=9x+36

180-36=9x

144=9x

x=16

plug in x to all the angles to find the real value
