B
Step-by-step explanation:
<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.

Answer:
d. 60
Step-by-step explanation:
According to Gay Lussac's Law
P1/T1=P2/T2 where
P1= Pressure at the start, T1 = initial Temperature
, P2= Final Pressure, T2 =Final Temperature
T1=P1*T2/P2= 7*420/49=60
