9th Grade Honors Geometry
Answer:
The Correct Answer is 4!
Step-by-step explanation:
We know on triangle 1 that 2 of the sides are 2 and 4 and there a right angle, an angle that has 90 degrees
with this we can calculate the top angle to be 26.565 which combined on both sides is equal to 90, lust you will then have to subtract 90 minus 26.565 and you will get 63.435. Now that we know than the top angle is equal to 63.435, the 2nd angle is equal to 90 degrees which by the way resembles a right angle, and that 1 side of the 3 sides is 2 we can conclude though the triangle formula that...

Answer:
10.-8/-2 can't represent calculating a mean change in score because a mean change in score is counted by adding up the scores & then dividing it by the number of the scores. As a number of scores can never be negative, so -8 can't be divided by -2 . So, -8/-2 can't represent this.
