chord is the answer hope this helped
Answer:
Step-by-step explanation:
y=mx+b
m=(y2-y1)/(x2-x1)
m=(90-65)(/(200-100)=25/100=1/4
y=x/4+b, using point (100,65)
65=100/4+b
65=25+b
b=40
y=x/4+40 or more neatly
y=(x+160)/4
Following these steps you should have no problem with second problem.
If it is a triangle it is 1 1/4.
3/8+3/8+4/8= 10/8
Simplify to 1 2/8 and it can be simplified again to 1 1/4
DOB
that is from 55 to 145
acute means angle is less than 90 degrees
right means equal to 90
obtuse means greater than 90
so
55 to 145
145-55=90
it is right angle
