Choice 2
You need to know line WX is congruent to line WZ. WY is a reflexive side so means it is equal in both triangles. Angle XWY and angle ZWY are congruent as marked in the picture so in order to know if Triangle XWY and Triangle ZWY by the SAS postulate, you need to know if sidez WX and WZ are congruent.

Mike is playing cards with his sister when he draws a card from a pack of 35 cards numbered from 1 to 35 what is the probability

Ganezh [65]

1/5 because there are 7 numbers divisible by 5 from 1 to 35. 5,10, 15, 20,25,30,35, and out of those there are 35 cards, 7 out of 35 or 7/5 can be simplified to 1/5.

riadik2000 [5.3K]

Answer:

Dharma and Jorge should purchase a group plan.

They could save $9.55

Step-by-step explanation:

A group plan will cost an average of $135.95 per month.

An individual plan will cost an average of $72.75 per month.

Two individual plans will cost an average of

$\$72.75\cdot 2=\$145.50$

per month.

Since $145.50 > $135.95, Dharma and Jorge should purchase a group plan.

They could save

$\$145.50-\$135.95=\$9.55$

posledela

Answer:

B. 103°

Step-by-step explanation:

Supplementary angles add up to 180°, so we can find the measure of angle 2 by subtracting 77 from 180

180 - 77

= 103

So, m∠2 is 103°
