Help The first one is what is on sale and the bottem is what needs to be solved!

Hatshy [7]

Answer:

jacket 80

shoes 32 and 16

shirt 9 , 8.04, 4.08

Step-by-step explanation:

you need to multiply the original cost by the percentage off and then subtract from the original

example

Jacket is originally priced at $120 it is on sale for 1/3 off which means that if you divide 120 by 3 you will get 40. but you would have to subtract the 40 from 120 giving you 80

What is the measure of angle c? (Brainliest and Bonus points for best answer)

k0ka [10]

Answer:

$\displaystyle 65°$

Step-by-step explanation:

Angle <em>b</em> and 135° form a <em>linear pair</em>, so when summing them up to 180°, you will have 45° left over:

$\displaystyle 180° = 135° + m∠b; 45° = m∠b$

Now, by the <em>Vertical</em><em> </em><em>Angles</em><em> </em><em>Theorem</em>, angle <em>a</em> and 70°, in this case, are to be in <u>congruence</u> with each other, so you have that.

Now you must find the the measure of angle <em>c</em> sinse you have already found the measure of two angles already:

$\displaystyle 180° = 45° + m∠c + 70° → 180° = 115° + m∠c; 65° = m∠c$

I am joyous to assist you at any time.
