Answer:

In your console (ctrl + shift + j), the letter a would appear. Beneath that, the letter c would appear.

Step-by-step explanation:

This is because the val2 is not less than or equal to 3. The second condition that's inside the first condition is true but since the first condition is false, the second condition would not run.

In △ABC,a=34, b=18, and c=17. Find m∠A.<br><br> A. 14.1<br> B. 132.6<br> C. 152.5<br> D. 101.5
igomit [66]

Answer:

C.  m < A = 152.5 degrees.

Step-by-step explanation:

Use the Cosine Rule:

a^2 = b^2 + c^2 - 2.b.c.cos A

34^2 = 18^2 + 17^2 - 2.18.17 cos A

2.18.17 cos A = 18^2 + 17^2 - 34^2

cos A =  (18^2 + 17^2 - 34^2) / (2.18.17)

cos A = -0.88725

m < A = 152.5 degrees.

A shopkeeper bought wheat for Rs. 35000. Due to leakage in the godown 1/7 of the total wheat was spoiled. He sold the good wheat
Alekssandra [29.7K]

Price of spoiled wheat=

\\ \sf\longmapsto 35000\times \dfrac{1}{7}

\\ \sf\longmapsto 5000

  • Good wheat cost price=35000-5000=Rs 30000

He sold good wheat at a gain of 10%

\\ \sf\longmapsto Gain=\dfrac{10}{100}\times 30000

\\ \sf\longmapsto Gain=3000

Now

\\ \sf\longmapsto Sold\:Price=30000+3000=\boxed{\bf{33000}}

<h3>______________________</h3>

  • He sold spoiled wheat at a loss of 25%

\\ \sf\longmapsto Loss=\dfrac{25}{100}\times 5000

\\ \sf\longmapsto 1250

Now

\\ \sf\longmapsto Sold\: Price=5000-1250=\boxed{\bf{3750}}

<h3>______________________</h3>

Total SP:-33000+3750=36750

  • He got a gain

\\ \sf\longmapsto Gain\%=\dfrac{36750-35000}{35000}\times 100

\\ \sf\longmapsto Gain\%=\dfrac{1750}{350}

\\ \sf\longmapsto Gain\%=5\%
