Answer:

1. Angles: <F=<J, <H=<H, <G=<K

Sides: FG/JK, GH/KH, FH/JH

2. 1/4 3. 5/2 4. X=12 5. 122.5 units 6. x=8; y=35 7. X=3 8. x=25 9. x=12 10. x=15 11. X=14 12. x=13

Step-by-step explanation:

2. 4/8 =1/4

3. 10/4=5/2

4. 5x=60(x=12)

5. 7(35)/2: 245/2= 122.5 units

6. x/28= 6/21: 21x=168: x=8

7. 49/14= 9(x+1)/(x+5): 49(x+5)=9(x+1)+14: 49x+245=126x+14: 245-14=126x-49x: 231=77x: x=3

8. 52/91=x+3/2x1: 52(2x-1)= 91(x+3): 104x-52=91x+273: 13x=325: x=25

9. 5x-3/3x+2= 60/40: 60(3x+2)= 40(5x-3): 200x-120=180x+120: 200=180x+120: 20x=240: x=12

10. 168x-280=160x-60: 8x-120: x=15

11. 12/x+1= 32/3x-2: 12(3x-2)= 32(x+1): 36x-24=32x+32: 4x=56: x=14

12. x+4/2x-7= 51/57: 57(x+4)= 51(2x-7): 57x +228=102x-357: -45x = -585: x=13

For a particular event, 771 tickets were sold for a total of $3037. If students paid $3 per ticket and non-students paid $5

BlackZzzverrR [31]

Answer:

Number of student tickets were sold = 409

Step-by-step explanation:

Total number of tickets sold = 771

I.e Students ticket (S) + Non students ticket(N S) = 771

Total amount to be paid for tickets = $ 3037

Amount paid by students per tickets = $3

Amount paid by non-students per tickets = $5

So, according to question

S + NS = 771

3 S + 5 NS = 3037

Solve both equations

5 S + 5 NS = 771 × 5

3 S + 5 NS = 3037

so ,

(5 S + 5 NS) - (3 S + 5 NS ) = 3855 - 3037

Or, 2 S = 818

I.e S = $\frac{818}{2}$ = 409

Hence, The number of student tickets were sold = 409 Answer

In a right triangle, <A and <B are acute. Find the value of sin A, when tan A = 8/15

finlep [7]

Answer:sinA=8/17

Step-by-step explanation:

Using Pythagoras principle

x=√(15^2+8^2)

x=√(15x15+8x8)

x=√(225+64)

x=√(289)

x=17

SinA=opposite/hypothenus

SinA=8/17
