<h3>
Answer: w = 31</h3>
===================================================
Explanation:
For any triangle, the interior angles always add to 180
(angle1)+(angle2)+(angle3) = 180
(w) + (4w-6) + (w) = 180
(w+4w+w) - 6 = 180
6w - 6 = 180
6w - 6+6 = 180+6 .... adding 6 to both sides
6w = 186
6w/6 = 186/6 ..... divide both sides by 6
w = 31
------------------------------------
Extra info:
This value of w leads to
4w-6 = 4*31-6 = 118
The three angles of the triangle are: 31, 118, 31
Because we have two congruent angles, this means the triangle is isosceles. The sides opposite the congruent angles are the same length.
The distance rounded to the nearest tenth is 333.7 kilometers
Answer
-15
Step-by-step explanation:
-13 +24=11
11-46=-35
-35+20=-15
Answer:
18.5
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
every triangle adds up to 180 sort of, in this case, turn 4 into 40. 40+20=60 so add 80 to be 180!!!
