sin = opp/hyp
sin A = 16/20= 4/5


As we know if powers are there is multiplication with same base gets added and with division gets substracted.



Answer: smaller number = 5, bigger number = 8
<u>Step-by-step explanation:</u>
Let x represent the smaller number
and y represent the bigger number.
The sum of 2 times the smaller number and 3 times the bigger number is 34.
EQ1: 2x + 3y = 34
Two times the bigger number is subtracted from 5 times the smaller number is 9.
EQ2: 5x - 2y = 9
Solve the system of equations using the Elimination method:
EQ1: 2x + 3y = 34 → 2(2x + 3y = 34) → 4x + 6y = 68
EQ2: 5x - 2y = 9 → 3(5x - 2y = 9 ) → <u> 15x - 6y</u> = <u>27 </u>
19x = 95
<u> ÷19 </u> <u>÷19 </u>
x = 5
Substitute x = 5 into either equation to solve for y:
EQ2: 5x - 2y = 9
5(5) - 2y = 9
25 - 2y = 9
-2y = -16
y = 8
The smaller number (x) is 5 and the bigger number (y) is 8.
