Angle 12 and Angle 10 are vertical angles.
A + C
(-5, -7) is 7 units to the left of point H
(-7, 7) is more than 7 units up and left of point H
the x axis is at (infinity, 0), being only 7 points up from point H
Answer:
How old are the students in math class?
Step-by-step explanation:
A statistical question is one that can be answered by collecting data and where there will be variability in that data. For example, there will likely be variability in the data collected to answer the question, "How much do the animals at Fancy Farm weigh?" but not to answer, "What color hat is Sara wearing?".
Answer:
Step-by-step explanation:
Easy. I got it right.
Step-by-step explanation:
We know:
The sum of the measures of acute angles in a right triangle is equal 90°.
Therefore
(1) A + B = 90°
(2) 90° + B + C = 180° - angles on a straight line
(3) from (2) B + C = 90° → B = 90° - C
(4) from (1) and (3) A + (90° - C) = 90° → A - C = 0
Therefore
A = C → ∠A ≅ ∠C
