Answer:
30.25
Step-by-step explanation:
All angles of a line must add up to 180. Since we already know that one angle is 90 degrees, we know that the other angles should add up to 90 degrees in order for all of the angles to add up to 180 degrees:
(3x-7)+(x+8)=90
4x+1=90
4x=89
x=22.25
22.25+8= 30.25
Answer:
55+x+74+54= 180 degree ( being the sum of all angle of the triangle )
or, 183 +x = 180degree
or, x=(180-183)degree
or, x= -3degree ans
