see the attached figure with letters
we have that
cos(alfa) triangle ABD=12/y
and
cos(alfa) triangle ABC=y/28
then
12/y=y/28----------> y²=12*28=336----------> y=√336=4√21
y=4√21
<span>applying the Pythagorean theorem triangle ABC
</span>(16+12)²=x²+y²----------? x²=28²-(4√21)²--------> x²=784-336
x=√448=8√7
the answer is x=8√7y=4√21
I’m pretty Sure that the answer would be 20 because 25 to the power of 2 would be 50 and 15 to the power of 2 is 30 and 50 - 30 =20
Answer:
1. $329.60
2. $824.00
Step-by-step explanation:
1.03 x 2= 2.06
2.06 x 160= 329.60
1.03 x 5= 5.15
5.15 x 160= 824
