Your making big several purchases from the b better electronic store. you can buy from this store online or in a physical store. you have a coupon for 20% off that can only be used in the physical store and a 20.00 coupon that can only be used online. the sales tax of 7.5% only applies to the physical store. shipping for the online store is a flat rate of 8.99 or free for purchases over 75.00. which way of purchasing would save you the most money?

I can write give you an answer with an assumption. Say you want to buy $500 worth of products. If you go to the store, you get 20% off, but you pay 7.5% tax on it so:
$500-20%=$400
That's $100 off makes sense because $100-$20= $80x5=$400
you don't get 20% off sales tax, so we do 
$400+7.5%=$430
That's $30 in taxes.

If you would do it online, it would be:
$500-$20 online coupon is = $480
shipping is free because I'm over $75

So which one is less? The in-store purchase because it's $430 vs online is $480. Online is $50 more than in-store. 

Answer: question no. 1 -a. yes, the sides are in the ratio 2 : 5.question no. 2 -b. 59°question no. 3 -c. angles x and y are remote interior angles.question no. 4 -d. 90°, 45° and 45°question no. 5 -b. mn and qrstep-by-step explanation: question no. 1 -rs : xu = 3 : 7.5 = 2 : 5rt : x? = 6.4 : 16 = 2 : 5st : u? = 6 : 15 = 2 : 5as the ratios of all sides are equivalent, the triangles must be congruent and the sides must be proportional.therefore, the answer is: a. yes, the sides are in the ratio 2 : 5.question no. 2 -in the second diagram, angle b is the only letter not shown. therefore, the number must be equivalent to angle b.if we substitute the value of angle b as being 22° in the first diagram, we can now use the angle sum of a triangle to obtain the value of angle a.angle sum of a triangle = 180°therefore: let angle a = aa + 99 + 22 = 180a = 180 - 99 - 22a = 59°therefore, the answer is: b. 59°question no. 3 -angles x and y don't share the vertex of the triangle with the exterior angle w. remote interior angles don't share a vertex of a triangle with an exterior angle. this means that angles x and y are remote interior angles.therefore, the answer is: c. angles x and y are remote interior angles.question no. 4 -the sum of all interior angles of a triangle must be equivalent to 180°.90°, 45° and 45° are the only set of angle measures that are equivalent to 180°.therefore, the answer is: d. 90°, 45° and 45°question no. 5 -the only pair of sides stated in the options which are corresponding are mn and qr.therefore, the answer is: b. mn and qr.
