Answer:
Step-by-step explanation:
Given that,
The value of 
We need to find an expression for 
. To find it, put the value of n as (n-1). So,
Hence, the value of S(n-1) is equal to 
.
<IMK=<GMH because they are vertical angles. Therefore:
84=4x
<em>*Divide both sides by 4*</em>
21=x
<IMK+<KMH=180 because they are supplementary angles. Therefore:
84+<KMH=180
<em>*Subtract 84 from both sides*</em>
<KMH=96

Answer: A, x = square root of 60.
Step-by-step explanation:
Use the Pythagorean Theorem, a^2 + b^2 = c^2.
8^2 = 2^2 + x^2
x^2 = 8^2 - 2^2
x^2 = 64 - 4
x^2 = 60
x = sqrt of 60
Answer:
x = -3
y = -1
Step-by-step explanation:
in the given question :-
=》x - 4y = 1
=》x = 4y + 1
now replacing the value of x as ( 4y + 1 ) in equation (2)
=》3x + 2y = -11
=》3 (4y + 1) + 2y = -11
=》12y + 3 + 2y = -11
=》14y = -11 - 3
=》y = -14 ÷ 14
=》y = -1
now, putting the value of y in equation (1)
=》x - 4y = 1
=》x - ( 4 × -1 ) = 1
=》x + 4 = 1
=》x = 1 - 4
=》x = -3
