Tiana has a triangular piece of construction paper. she cuts the paper into three pieces.
then, she rearranges the three pieces as shown.
what do the pieces of tiana's triangle show?
a
the sum of the interior angles of a triangle is equal to the sum of the interior angles of a quadrilateral
the sum of the interior angles of a triangle is equal to the measure of a straight angle.
the sum of two interior angles of a triangle is equal to the measure of a right angle.
the sum of the interior anales of a triangle is equal to the sum of the interior anales of a pentagon

  The sum of the interior angles of a triangle is equal to the measure of a straight angle

Step-by-step explanation:

The bottom edge of the second figure (where the colored angles all have the same vertex) is a straight angle. Hence that figure shows ...

  The sum of the interior angles of a triangle is equal to the measure of a straight angle

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

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:
