  • HJ = 23.5 in

\textsf{  \underline{\underline{Steps to solve the problem} }:}

Take HJ = a, GH = b and GJ = c

  • a = b + 2

  • c = a + b - 17

  • a + b + c = 73

put the value of a from equation 1 in equation 2

  • c = (b + 2) + b − 17

  • c = 2b − 15

now, put the value of a and c in equation 3

  • b + 2 + b + 2b − 15 = 73

  • 4b − 13 = 73

  • 4b = 86

  • b = 21.5 in

Now, we need to find HJ (a)

  • a = b + 2

  • a = 21.5 + 2

  • a = 23.5 in

{ \qquad \large \sf {Conclusion} :}

  • HJ = 23.5 in

I need help with trigonometry
MrMuchimi

Answer:

In alphabetic order:

x can be found with pythagorean theorem, since triangle ADC is right in D.

x= \sqrt {7^2-2.2^2} \approx 6.6

y and z are 7 times respectively the sine and cosine of angle ACB.

y= 7sin\ 52\° \approx 5.5\\z=7 cos\ 52\° \approx 4.3

Finally, \theta  can be calculated by determining the arc sine (or inverse sine) of the ratio CD over AC

\theta = sin^{-1} (\frac{2.2}7) \approx 18.3\°

Raghu invested Rs. 60000 and Nazar Rs. 100000 and started a business. Within one month a profit of Rs. 4800 was obtained. Raghu
amm1812

Answer:See explanation

Step-by-step explanation:

Raghu investment = Rs 60,000

Nazar investment = Rs 100,000

Raghu profit = 1800

Nazar profit = 3000

Raghu invested Rs. 60000 and Nazar Rs. 100000. The ratio of their investments will be:

= 60000/100000

= 3/5

= 3:5.

The ratio of their profit will be:

= 1800/3000

= 3/5

= 3:5

Since we have identical ratio, we can then say that the investment and the profit are divided proportionally.

What is the total amount in an account that has had $45 per month added into it for 30 years and grew with an annual interest ra
Lena [83]

The Future Value of an Annuity is given by:FV = P [(1 + r)^n -1 / r] where the periodic payment P = $45  
N = number of period = 360. And r = rate per period = (0.08/12) = 0.0066667  
So we have 45[((1 + 0.0066667)^(360) - 1)/ 0.0066667] = $16, 405. 27

Step-by-step explanation:

y = 4 + b

Output is y

Input is b

We are asked to find out what we get if we input 5.

y = 4 + 5

4 + 5 = 9

y = 9

9 is the fifth output
