Given:
Consider the given expression is:
To find:
The simplified form of the given expression.
Solution:
We have,
Taking LCM, we get
Therefore, the required simplified fraction for the given expression is .
Answer-146
Add all the numbers and because 360 is how much a circle is equal to subtract 360 by 68 which is what you will get if you add the numbers up and after you will get 246 so just divide 246 by 2 and u get 146
A <u>triangle</u> is an example of a class of <em>figures</em> referred to as <em>plane shapes</em>. It has <u>three</u> straight <u>sides</u> and <u>three</u> internal <u>angles</u> which sum up to . The <em>measures</em> of the internal <u>angles</u> of the <u>triangle</u> given in the question are A = , B = , and C = .
A <u>triangle</u> is an example of a class of <em>figures</em> referred to as <em>plane shapes</em>. It has <u>three</u> straight <u>sides</u> and <u>three</u> internal <u>angles</u> which sum up to .
Considering the given question, let the <u>sides</u> of the triangle be: a = 6 km, b = 6.5 km, and c = 7 km.
Apply the <em>Cosine rule</em> to have:
= + - 2ab Cos C
So that;
= + - 2(6 * 6.5) Cos C
49 = 36 + 42.25 - 78Cos C
78 Cos C = 78.25 - 49
= 29.25
Cos C =
= 0.375
C = 0.375
= 67.9757
C =
Apply the <em>Sine rule</em> to determine the <u>value</u> of B,
=
=
SIn B =
= 0.861
B = 0.861
= 59.43
B =
Thus to determine the value of A, we have;
A + B + C =
A + + =
A = - 127.4
= 52.6
A =
Therefore the <u>sizes</u> of the <em>internal angles</em> of the triangle are: A = , B = , and C = .
