Answer:
x = 15
Step-by-step explanation:
Both legs of the triangle are equal, with it being an isosceles triangle. You can tell the base is not equivalent due to there being the little arrow symbol on the base and not the legs.
To solve for x, add up the values on both legs and solve the equation from there.
Equation - 2x + 10 = 40
Subtract - 2x = 30
Divide - x = 15
To make sure you have the right answer, check your work.
Equation - 2x + 10 = 40
Replace - 2(15) + 10 = 40
Multiply - 30 + 10 = 40
Add - 40 = 40
The value of x will be equal to 2.477.
<h3>What is a logarithm?</h3>
The logarithm is the inverse function of exponentiation in mathematics. That is, the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised in order to obtain that number x.
The given expression will be solved as follows;-
Taking Log on both sides.
(x-2) Log5 = Log 8
( x-2) = Log8 / Log 5
(x - 2) = Log 8 - Log 5
(x - 2 ) = Log 3
x-2 = 0.477
x = 2.477
Therefore the value of x will be equal to 2.477.
