Answer:
∠1=160° and ∠2=20°
Step-by-step explanation:
Let ∠1 = x
∠2 = y
as these two angles are supplementary their sum is 180
that x+y=180 ----(A)
Also given that ∠1 is 20 degree less than nine times the size of ∠2.
Hence
x=9y-20
putting value of x in A and solving for y
9y-20+y=180
10y=180+20
10y=200
y=10
Putting this y in A
x+10=180
x=160

Answer:
y=-2/7x+6
Step-by-step explanation:
first write this in y=mx+b format, y=7/2x−2
then write the perpendicular line, which is the opposite & negative of m
y=−2/7x-2
then remove b
y=−2/7x+b
plug in the numbers
(7,4) y= 4 x=7
4=-2/7*7+b
b is 6
so put the numbers back in
y=-2/7x+6
hope this helps and have a great day
