Answer:
y = -1/3x
Step-by-step explanation:
The slope of that are perpendicular lines are negative opposites of each other. If a line has a slope of 3, then a line perpendicular to it will have a slope of (-(1/3)).
Use the equation of a line in point-slope form to solve this;
y = mx + b
where "m" is the slope and "b" is the y-intercept.
Substitute the slope in;
y = (-1/3)x + b
Since it passes through the origin, then it has no y-intercept, therefore the equation of the line is;
y = -1/3x
Answer:
m<1 = 57°
m<2 = 74°
Step-by-step explanation:
m<1 = 57° (alternate interior angles are congruent)
m<B + m<C + m<2 = 180° (sum of interior angles of a triangle)
57° + 49° + m<2 = 180° (substitution)
106° + m<2 = 180°
Subtract 106° from both sides
m<2 = 180° - 106°
m<2 = 74°
The equation will look like this..
Y= -2/3x
There is no need to add a plus zero because the equation doesn't need it. The slope is always follow by the X.
Answer:
In the figure ∠ABO and ∠BCO have measures equal to 35°.
Step-by-step explanation:
Measure of arc AD = 180-measure of arc CD= 180-125 =55
m<AOB= 55 ( measure of central angle is equal to intercepted arc)
<OAB= 90 degrees (Tangent makes an angle of 90 degrees with the radius)
In triangle AOB ,
< AB0 = 180-(90+55)= 35 degrees( angle sum property of triangle)
In triange BOC ,< BOC=125 ,
m<, BCO=35 degrees
Answer:
Measure of angle s:
Sum all angles of triangle is = 180 degrees
So,
31 + 58 + x = 180
x = 180 - 31 - 58
x = 91
Measure of angle s: 91 degrees
ST = 17.005
RT = 33.012
