Answer:
Becky, because her justification for the second statement should be "definition of supplementary angles" rather than "angle addition postulate."
Step-by-step explanation:
Becky completed the proof incorrectly because her justification for the second statement is not totally correct.
Angle addition postulate does not really apply here, as the sum of 2 angles may not give you exactly 180°.
However, the second statement, m<AKG + m<GKB = 180° and m<GKB + m<HKB = 180°, can be justified by the "Definition of Supplementary Angles".
The sum of supplementary angles = 180°.
Therefore, Becky completed the proof incorrectly.
Answer:
It would be losing 300.
Step-by-step explanation:
The opposite of gaining is losing the integer would be -300
The equation for the area of a right triangle is 1/2 x base x height. therefore on the first triangle i would assume 4 and 3 are the base and the height. therefore the hypotenuse would be 5 because a^2 + b^2 = c^2. a and b are the base and the height and c is the hypotenuse. so if you multiply 3 by 4,3 and 5. youre new base and height would be 12 and 9 and the hypotenuse would be 15. if you plug 12 and 9 (the base and the height) into the formula for the area of a right triangle (1/2 x base x height) the area of the new triangle would be 54. hope this helps!!
