You need to write it out such as number 8 would be 10x10x10x10 so for every number on top you multiply the number by itself
Answer: 0.72/20; 1.98/20; 17.3/20
0.036 * 10/10 = 0.36/10 * 2/2 = 0.72/20
0.099 * 10/10 = 0.99/10 * 2/2 = 1.98/20
0.865 * 10/10 = 8.65/10 * 2/2 = 17.3/20
Answer:
Step-by-step explanation:
First use the fact that the sum of interior angles of a triangle is 180° to find the measure of the missing angle
in ΔDEF we have 180 -68 -81 = 31°
in ΔABC we have 180 -68 -33 = 79°
the measure of the angles in ΔABC and ΔDEF are different 33°, 68°, 79° ≠81°, 68°, 31°so the two triangles are not congruent.
