Question

ABC is a triangle in which < B = 900. Draw and label a sketch, then calculate the length of the third side of the triangle of side AB = 6m, BC = 8m.






(A) 14m

(B) 10m

(C) 12m

(D)


11m

Answer 1

Answer:

We have the length of 2 of the 3 sides of a right triangle: AB=6m, BC=8m , so we're looking for AC. Using the theorem Pythagoras gave us A²+B²=C².

6m²+8m²=C²

36m+64m=√100m =10m
