Answer:
32
Step-by-step explanation:
The shape in image is an equilateral triangle which means all of it's angles has equal measurements:
2x - 4 = 5y and that is equal to 60 degrees
2x - 4 = 60 add 4 to both sides
2x = 64 divide both sides by 2
x = 32
It would be a straight line
The second and third highest temperatures were -8 and 7, you just need to state a value between those; such as 3 or 4.
Hope this helps :)
The answer would be b, hope it helps!
