Answer:
k=-27 i think
Step-by-step explanation:
To find if it's a right triangle, we use the Pythagorean Theorem of a² + b² = c² where a and b are the legs of the triangle (the shorter measurements) and c is the hypotenuse (the biggest measurement).
28² + 34² = 43²
784 + 1156 = 1849
1940 ≠ 1849
No. This is not a right triangle. The sum of the squares of the shorter measurements (AKA the legs) do not equal the square of the biggest measurement.
1. 90°
2. 25°
1. A straight line has an angle of 180°, and if one part of it measures 90°, then that means the other part has to measure 90°.
2. Again, a straight line measures 180°, and if one part measures 155°, the other part must measure 25° in order for the entire angle to measure 180°.
