Eddie is correct about his prediction. A coin has two sides, one head, one tail, so there is a 50% chance that it will land heads every time Eddie flips the coin. I would tell Eddie that his prediction is reasonable and mathematically correct.
Answer:
The absolute value of -5 is...5
Step-by-step explanation:
Answer:
22.5° and 67.5°
Step-by-step explanation:
The sum of complementary angles equal 90°.
Given that one of the complementary angles is 3 times larger than the other, let "x" represent the other angle.
Thus, the following expression can be written to represent this case:

Solve for x

Divide both sides by 4


The measure of the complementary angles are:
x = 22.5°
3x = 3(22.5) = 67.5°
Step-by-step explanation:




Angle 1 is 79
Angle 2 is 11.
Look at the picture.
We have the similar triangles (AAA). Therefore the lengths of the sides are in proportion:

<em>multiply both sides by 8</em>
