Answer:
∠ABC = 60°
Step-by-step explanation:
All angles in equilateral triangles are equal.
all angles in triangles added together = 180°
180°/3 = 60°
All angles in equilateral triangles are equal to 60°.
Answer:

Step-by-step explanation:
let x° be temperature when he woke up. Given that the temperature rose by 11° then later dropped by 14°. Also let
be temperature at time she went to bed.
-We add the temperature rise and subtract the temperature drop to find temperature at time she goes to bed.
-The temperature relative to time of waking up can be expressed as:

Hence, the temperature relative to the time Iko woke up is (x-3)°
Step-by-step explanation:
The largest possible ellipse will have a semi-minor axis of 2 feet and a semi-major axis of 4 feet. If we center the board on the origin of the cartesian coordinate plane, we can derive the location of the foci and thus, the length of string he will need:
x^2 / 16 + y^2 / 4 = 1
