Answer:
71.49134 feet
Step-by-step explanation:
Side a = 112
Side b = 99
Side c = 71.49134
Angle ∠A = 80.37° = 80°22'11" = 1.40272 rad
Angle ∠B = 60.63° = 60°37'49" = 1.0582 rad
Angle ∠C = 39° = 0.68068 rad

Answer:
3) x = 15; 95 and 85 4) x = 12; 98 for both angles
Step-by-step explanation:
2x + 65 + 3x + 40 = 180 Set the equations equal to 180
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10 Set the equations equal to each other
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98
Answer: 14/25 = 56/100
11/20 = 55/100
14/25 > 11/20
Step-by-step explanation:
The least common multiple of 20 and 25 is 100.
(100 = 20*5, 25*4)
So we can take the common denominator 100.
14*4/25*4 =56/100. ∴14/25 = 56/100
11*5/20*5 =55/100. ∴11/20 = 55/100
56>55
∴56/100 > 55/100
∴14/25 > 11/20
Hope it's good;)
16, 048÷ 1/8
First you have to turn the 1/8 upside down and change the division into multiplication. So;
16,048 x8/1
This is the same as 16,048 x 8. And that is 128384. So the answer is 128384. Always know that when you are dividing fractions, the fraction being divided (fraction at the right) has to be turned upside down and the division changed to multiplication. Hope I helped.
