Answer:
x=67
Step-by-step explanation:
x+23+90=180
x+113=180
x=180-113
answer is 67
let use angle sum property
the sum if triangle is 180
if it is perpendicular it is 90 degree
180 is equal to 23+90+x
180 is equal to 133x
x is equal to 180-133
so we get 67
The 3rd answer i think
2.8 < x -0
answer is 8$
