Answer: A △ABC such that the bisectors of ∠ABC and ∠ACB meet at a point O.
To prove :
∠BOC=90
o
+

1
∠A
Step-by-step explanation: In △BOC,
∠1+∠2+∠BOC=180
o
In △ABC,
∠A+∠B+∠C=180
o
∠A+2(∠1)+2(∠2)=180
o

∠A
+∠1+∠2=90
o
∠1+∠2=90

∠A
If both points have either the same 'x' value or the same 'y' value, then they both lie on the same grid line...:)
Answer:
The first one is correct.
The second one is also correct!
Hope this helps :)
The coordinates of point r(-8,0).
<h3>What is midpoint formula in coordinate geometry?</h3>
The coordinates of the point r(x,y) which divides the line segment joining the points p(
,
) and q(
,
) internally in the ratio :
are

Given that,
Two end points on the line q(-14,0) and s(2,0). point r(x,y) is the partition of the line segment from q to s in a ratio 3:5
= 3 and
= 5
By using the midpoint formula




Hence, The coordinates of point r(-8,0).

Answer:
3 hours
Step-by-step explanation:
First we can find how much money you had to pay for keeping the skates for the additional hours:
$7.70-$3.95=$3.75
Now we find how many hours you kept the skates...
$3.75/$1.25 per hour=3 hours
