Answer:
Step-by-step explanation:
In the given circle, 
is diameter and 
is tangent at point E.
is a semicircular arc.
Since, measure of semicircular arc is 180°
.... (2)
From equations (1) & (2)
By inscribed angle theorem:
By tangent secant theorem:
a(2a-3(1-a))+5(a-a^2)
distribute the inner most parenthesis
a( 2a -3+3a))+5(a-a^2)
combine like terms
a(5a-3) +5(a-a^2)
distribute both sets of parenthesis
5a^2 -3a +5a-5a^2
combine like terms
5a^2-5a^2 -3a+5a
2a
Answer:
6.75 or 6 3/4
Step-by-step explanation:
First take the whole number and multiply that by 3.
2*3=6
Now, take the fraction and multiply that times 3.
1/4 as a decimal is 0.25. You can ignore the decimal point right now, but you have to remember it is there later.
So, whithout the decimal point, 25*3= 75.
Now, you add the decimal. The 75 is now 0.75, with the decimal.
Add the whole number and the decimal, and you have your answer!
6+0.75=6.75. As a fraction this is 6 3/4
