Given ABC = DEF
m m find m

9514 1404 393

  10

Step-by-step explanation:

Corresponding angles of congruent triangles are congruent.

  angle B = angle E

  3v +4 = 8v -6

  10 = 5v

  v = 2

Then the measure of angle B is

  3v +4 = 3(2) +4 = 10 . . . measure of ∠B

10

Step-by-step explanation:

I hope this helps and good luck

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
