Question

Plz help me with this unknown side length in right triangle

Answer 1

Answer:

7 sqrt(2)= BC

7 sqrt(2)= AB

Step-by-step explanation:

sin 45 = opp / hyp

sin 45 = BC / 14

Multiply each side by 14

14 sin 45 = BC

Sin 45 = sqrt(2)/2

14 sqrt(2)/ 2 = BC

7 sqrt(2)= BC

cos 45 = adj / hyp

cos 45 = AB / 14

Multiply each side by 14

14 cos 45 = AB

cos 45 = sqrt(2)/2

14 sqrt(2)/ 2 = AB

7 sqrt(2)= AB
