3y=2(2+2y); 3y=4+4y; -y=4; y=-4;
Answer:
I don't know the answer to this one, sorry
CB = DA = √3*3+1*1 = √10
CD = BA = √2*2+1*1 = √5
Sum is 2√10 + 2√5 ≈ 10.8. So answer A.
4-190
190 divided by 4 is 47.5, so Rodney travels 47.5 miles per day.
if Rodney travel 190 miles in 4 days, at 47.5 miles to 190 to find out how far he would travel in 5 days. 190+47.5= 237.5
----------------------------
day #4-190 miles
day #5-237.5 miles
day #6-285 miles
Hey there! :D
Since the sides are equal in length, we know this is an isosceles triangle. It will have two equal angles.
We already know the vertex is 80 degrees, so the bottom two angles will be equal in measure. All angles in a triangle equal 180 degrees
180-80= 100
100/2= 50
x= 50
I hope this helps!
