Answer:

x=35

Step-by-step explanation:

A pentagon's sum of interior angles is 540 degrees.

Now, we can set up an equation.

(4x - 57) + (3x + 15) + 4x + (2x - 3) (3x + 25) = 540

Combine similar terms

16x - 20 = 540

16x = 560

<u>x = 35</u>

zepelin [54]

Answer:

<h2>cos 30°= 0.866</h2>

Step-by-step explanation:

Step one:

Applying the SOH CAH TOA principle

assuming all dimensions are in cm

Step two:

Given data

opposite= 1 cm

hypotenuse= 2 cm

<h3>we can now solve for θ</h3>

Sin(θ)= opp/hyp

Sin(θ)= 1/2

Sin(θ)= 0.5

θ= sin-1 0.5

θ= 30°

hence  from tables cos 30°= 0.866

tamaranim1 [39]

Answer:

The amount which Sunil own to the bank after two years is Rs 67 lakh and sixty thousand

Step-by-step explanation:

Given as :

The amount borrowed by Sunil for education loan = Rs 40 lakh

The rate of interest applied compounded annually  = 30%

The time period of loan is 2 years

Amount = Principal \times  (1 + \frac{Rate}{100})^{Time}

Or, Amount = 4000000 \times  (1 + \frac{30}{100})^{2}

Or,  Amount = 4000000 \times  (\frac{130}{100})^{2}

Or, Amount = 4000000 × ( 1.3 )²

Or, Amount =Rs 6,760,000

Hence The amount which Sunil own to the bank after two years is Rs 67 lakh and sixty thousand     Answer
