Answer:
This other side of the triangle is equal to about 11.7 cm
Step-by-step explanation:
In order to find out the third side of the triangle we will just use the Pythagoras Theorem.
Since we know the hypotenuse and we know one of the legs, in order to find the second leg we just substitute the values and solve the equation and so we get...
And so b ≈ 11.66190

Answer:
A
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosA = 
= 
= 
, thus
A = 
( ) ≈ 48° → A
Answer:
A≈254 cm^2
Step-by-step explanation:
The area of a circle is given by formula: π
r^2
π has a constant value of 3.14 And the radius of the circle is 9
c
