$29.99 is the final price.
"y" is the original price.
Subtract the savings from the original price to get the final price of $29.99.
70% = 70/100 = .70
y - (y x .70) = 29.99
y - .7y = 29.99
.3y = 29.99
.3y/.3 = 29.99/.3
y = 99.96667
y = $99.97 (rounded)
By asking on Brainly, you clearly don't care how you get the answer.
The part of interest is the law of sines tells you
.. A = arcsin((12/11)*sin(46°)) = 51.7° . . . or . . . 180°-51.7° = 128.3°
.. c = 11*sin(82.3°)/sin(46°) ≈ 15.2 . . . or . . . sin(5.7°)/sin(46°) ≈ 1.5
Selection D is appropriate.
Answer:
The two angles are 85 and 95 degrees
Step-by-step explanation:
Supplementary angles add to 180
Let x be one angle
The supplement is 10 less, ( x-10)
They add to 180
x+ ( x-10) = 180
2x -10 = 180
Add 10 to each side
2x-10+10 =180-10
2x= 190
Divide by 2
2x/2 =190/2
x=95
The other angle is 95-10 = 85
The two angles are 85 and 95 degrees
