BRAINLIEST OF CORRECT !! the side lengths of a triangle are 6, 8, and 12. is this a right angle?

C. no, because 6^2 + 8^2 12^2

step-by-step explanation:

a^2 + b^2 = c^2

6^2 + 8^2 = 12^2

36 + 64 = 144

100 144

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
