<span>B) 84 + z = 180, since 42*2=84, 180-84=96, z=96</span>

Nat2105 [25]
-k + 0.03 + 1.01K = -2.45 - 1.81k
0.01k + 0.03 = -2.45 - 1.81k
0.01k + 1.81k = -2.45 - 0.03
1.82k = -2.48

Determine whether the triangles are similar. or not.
mr Goodwill [35]

Answer:

A

Step-by-step explanation:

We know that ∠ABE ≅ ∠DBC because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠BAE and ∠DCB as they have different measures, so we'll have to find the measure of either ∠AEB or ∠BDC. Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is 180°, we know that m∠AEB=180-(53+42)=180-95=85°. Now, we know that ∠AEB ≅ ∠DCB because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by AA. Hope this helps!
