<span>The solution to the problem is as follows:
tan (3x) = sin(3x) / cos(3x)
let u = cos(3x), du = -3 sin(3x)
Integrating -1/3 du / u = -1/3 ln (u) = -1/3 ln (abs (cos(3x)) + constant

Alright!
The formula of area of a triangle is base x height /2
so you're given the height and hypotenuse.
Do the reverse of the pythagorean theorem to find the base
a^2= c^2 -b^2
c^2 is the hypotenuse and b^2 is the height
a^2= 10^2 - 8^2
a^2 = 100 - 84
a^2 = 16
a= (square root the 16)
a= 4 cm
now put these numbers into the formula for area of a triangle
bxh / 2
(4x8)/ 2
= 16 cm squared !!
hope that makes sense :)
I hope this helps you
m (A)=110 a=44
m (B)=40 b=28
m (C)=30 c=24
Answer:
x = 5
Step-by-step explanation:
GE is the angle bisector of quadrilateral DEFG,
Thus, by angle bisector property:
9x°= (5x + 20)°
9x = 5x + 20
9x - 5x = 20
4x = 20
x = 20/4
x = 5
