Answer:
The slope of line a is * also.
Step-by-step explanation:
Parallel lines have the same slope. Whatever number, fraction, variable, symbol is given for the slope of one line, the other must have the same number, fraction, variable, symbol, if they are parallel.
Answer:
Part 1) The measure of the exterior angle is 128°
Part 2) The measure of angle x is 30°
part 3) The value of x is 25 units
Step-by-step explanation:
Part 1)
step 1
Find the measure of the third internal angle of the triangle
Remember that the sum of the internal angles of a triangle must be equal to 180 degrees
Let
c----> the measure of the third internal angle
42+(9x-4)°+c°=180°
c=180°-42°-9x+4°
c=142°-9x
step 2
Find the value of x
we know that
c+(12x+8)°=180° ----> by supplementary angles
substitute
142°-9x+(12x+8)°=180°
3x=30°
x=10°
step 3
Find the measure of the exterior angle
(12x+8)°=(12(10)+8)°=128°
Part 2) Find the value of x
The figure show a equilateral triangle ( has three equal internal angles and three equal sides) and an isosceles triangle ( has two equal internal angles and two equal sides)
Remember that
The internal angles of a equilateral triangle is 60 degrees
so
The vertex angle of the isosceles triangle is equal to
180°-60°=120° ----> by supplementary angles
therefore
The base angle of the isosceles triangle is equal to
2x+120°=180°
2x=60°
x=30°
Part 3) we know that
if AB is a midsegment
then
(4x-10)/2=45
solve for x
4x-10=90
4x=100
x=25 units
I believe the answer is probability
