Triangle D E F is a dilation of triangle ABC with scale factor 2. In triangle ABC, the largest angle measures 82. What is the largest angle measure in triangle DEF?

82°

Step-by-step explanation:

Given: Triangle DEF is a dilation of triangle ABC with scale factor 2.

In triangle ABC, the largest angle measures 82°, then the largest angle measure in triangle DEF should be 82°.

So, the largest angle measure in triangle DEF = 82°

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest

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
