Answer:
3 is 15 degrees and 1 is 67 degrees
Answer:
Below.
Step-by-step explanation:
Area = 5(x + 3)
= 5x + 15
Perimeter = 2(x + 3) + 2(5)
= 2x + 6 + 10
= 2x + 16.
Answer:
y =
x + 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 10x + 1 ← is in slope- intercept form
with slope m = - 10
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, thus
y =
x + c ← is the partial equation
To find c substitute (5, 7) into the partial equation
7 =
+ c ⇒ c = 7 -
= 
y =
x +
← equation of line
