Answer:
This is pythagoras
A squared plus b squared equals c squared.
The unknown side is c as its the hypotenuse,
So the length of the first side is 6.4 this squared = 40.96
The other length is 12 as 6 is the radius so the diameter of the circle amd therfore the length of the triangle is 12.
12 squared is 144
144 + 40.96 = 184.96
The length of c squared is 184.96
To find the length of c alone we calculate the square root.
The square root of 184.96 = 13.6
? = 13.6
4x^2 + 8x + 12
Equivalent forms: x^2 + 2x + 3 and 8x^2 + 16x + 24.
The first equivalent form was created by dividing each term by 2, and the second equivalent form was created by multiplying each term by 2.
Answer:
Step-by-step explanation:
take 45 degree as reference angle
use sin rule
sin 45=opposite/hypotenuse
1/=x/2
do cross multiplication
x= *
x=2
x=2/
x=
pythagoras theorem
a^2+b^2=c^2
( )^2+y^2=(2 )^2
2+y^2=8
y^2=8-2
y=
