Answer:
Step-by-step explanation:
In the triangle ABC, m∠ABC=90°. Hence, it is right angle triangle.
--------1
In the triangle ABD, m∠ABD=90°. Hence, it is right angle triangle.
As 
, so
---------2
From equation 1 and 2,
I hope this helps you
Arc Length=Center Angle/360.2.pi.r
117,75=90/360.2.3,14.r
r=117,75/1,57
r=75
Step-by-step explanation:
ok so for number 1 you first have to group the like terms therefore you will now have:
9r-4r+8-6
and now you calculate:
9r-4r=5r
8-6=2
so that means 5r-2 is simplied version for no.1
for number you 2 you first multiply why is inside the brackets by what is in the outside:
2(x+3y)
2x+6y (simplified version)
hope this helps! no problem
