Answer:
B. 55°
Step-by-step explanation:
Note that the total angle measurements of a triangle is = 180°.
Add all the measurements together:
40 + y + 30 + y = 180
Simplify. Combine like terms:
(40 + 30) + (y + y) = 180
70 + 2y = 180
Isolate the y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First subtract, then divide.
Subtract 70 from both sides:
70 (-70) + 2y = 180 (-70)
2y = 180 - 70
2y = 110
Divide 2 from both sides:
(2y)/2 = (110)/2
y = 110/2
y = 55
B. 55° is your answer.

Answer:
Side 3 or side 4
Step-by-step explanation:
The ground has 6 sides
<u>Each side is:</u>
It is assumed that total distance is one cycle of 270 m.
Since no diagram attached, the start point X is the beginning of side 1.
<u>Then the distance covered is:</u>
As
- 2*45 m = 90 m < 108 m < 3*45 m = 135 m
the scouts reached the side 3 or side 4 of the ground depending on direction of movement (clockwise vs anti-clockwise)
