Answer:
Given: Line p is parallel to line r.
Alternate exterior angles states that two angles in the exterior of the parallel lines, and on opposite sides of the transversal.
Alternate exterior angles are non-adjacent and congruent.
[ Alternate exterior angles]
Since, Angles are congruent if they have the same angle measure in degrees
....[1] [by definition of congruent Angles]
Linear pair states that a pair of adjacent angles formed when two lines intersect.
therefore, by definition 
and 
forms a linear pair.
Since, linear pair are always supplementary.
is supplementary to
Supplementary angles states that two angles are supplementary that means they add up to measure 180 degree.
Substitute the equation [1] in above equation we get;
then, by the definition of supplementary angle ;
is supplementary to 
Answer:
20.25
Step-by-step explanation:
So it tell us that he is able to get 5 hits out of 7 and to find how much he could make if 210 chances
We solve what can be solved
Then we leave our variable alone
Last we solve
In this case we can see that he could make 147 hits out of 210 bats.
Thats 95 cents becuase nickel equals 5 and dime equals 10
so 5x5=25
and 7x10=70
so 70+25=95 cuz 0+5=5 and 7+2=9
Answer:
x°=96°
y°=88°
z°=151°
Step-by-step explanation:
55°+29°+×°=180°
×°=96°
96°+55°=z°
z°=151
then let variable A° be one of the inner angle of the triangle
A°+z°=180°
A°+151°=180°
A°=29°
finally adding all the inner angles will give us 180°
96°+y°-13°+29=180°
y°=88°
