Answer:
8!
Step-by-step explanation:
find numbers for school bus and car by multiplying percentages in decimal form 40% turns into .40 and 30 into .30
0.4x80 and 0.3x80 = 32 and 24. 32-24=8
The answer is B because C and D are not true. Angle-Angle theorem does not prove congruency. Hypotenuse-Leg does because having a hypotenuse means that the triangle is a right angle triangle, which means that 2 sides and an angle are congruent in the triangles. By Side-Side-Angle Theorem, the triangles are congruent.
