Answer:
Yes
Step-by-step explanation:
you labelled it correctly. angle a is across from side a, and vice versa. nice job!! :)
Answer:
23 hours
Step-by-step explanation:
So here we are trying to calculate Time which is Distance divided by Speed
Time = 
Firstly, we have to calculate the Speed which is = 
= 60
This means that the speed is 60 miles per hour or 60 mph.
Then to find the total time we take the Distance and divide it by the Speed:
= 35
So this means that his total trip took 35 hours so lets subtract 12 hours to get how many more hours: 35 - 12 = 23 hours
Tree height / 14 = 6 / 3.5
tree height = (14 * 6) / 3.5

5y=9

Answers:
The first blank is 180
The second blank is 60
======================================
The triangle sum theorem basically says that adding up all three angles of any triangle always leads to 180 degrees. So that's why
(angle1)+(angle2)+(angle3) = 180
x+x+x = 180
3x = 180
Divide both sides of that last equation by 3. This is to undo the multiplication of 3 done to x.
3x = 180
3x/3 = 180/3 ... divide both sides by 3
x = 60
Each angle of this equilateral triangle is 60 degrees. In an equilateral triangle, all three sides are the same length. Also in an equilateral triangle, all three angles are the same measure and always 60 degrees.
