We know that side NM is parallel to side XZ. If we consider side NY the transversal for these parallel lines, we create angle pa

irs. Using the corresponding angles theorem, we can state that ∠YXZ is congruent to ∠YNM. We know that angle XYZ is congruent to angle what by the reflexive property. Therefore, triangle XYZ is similar to triangle NYM by the what similarity theorem.

See the picture attached.

We know:
NM // XZ
NY = transversal line
∠YXZ ≡ ∠YNM

1) <span>We know that ∠XYZ is congruent to ∠NYM by the reflexive property.</span>

The reflexive property states that any shape is congruent to itself.
∠NYM is just a different way to call ∠XYZ using different vertexes, but the sides composing the two angles are the same.
Hence, ∠XYZ ≡ <span>∠NYM</span> by the reflexive property.

2) Δ<span>XYZ is similar to ΔNYM by the AA (angle-angle) similarity theorem

The AA similarity theorem states that if two triangles have a pair of corresponding angles congruent, then the two triangles are similar.
Consider </span>Δ<span>XYZ and ΔNYM:
</span>∠YXZ ≡ <span>∠YNM
</span>∠XYZ ≡ ∠NYM
Hence, ΔXYZ is similar to ΔNYM by the AA similarity theorem.

I need help with a math question but apparently everyone is dead today..

The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps

Well add them all up. : 10+15+8+7=40. There are 8 white balls out of 40. 8/40. Find the GCF of them both and simplify them.

8=8 so 8/8 = 1
40=8 so 40/8 = 5 so 1/5 is your answer.

B. is your answer.

Hoped I helped!
