Step-by-step explanation:
#4 = B
Explanation= Because C&A are the same angle measurement, and the 90 angle is along a straight line making the other angle 90, and the triangles share the same side the postulate you can use is AAS because you can prove that the triangles share 2 common angles and 1 common side
#5 = B
Explanation= Because the triangles already have 1 congruent angle, and 1 congruent side the only thing left we can prove is that because the triangles mirror each other, they have congruent opposite angles (may be called vertical angles) as well so they have 2 angles and 1 side in common which tells you to use AAS
441 to the nearest ten is 440
345 to the nearest ten is 350
The sum is;
440 + 350 = 790
It would be 1.3 bescuse its only 2 significant figures
