The tan(-x) is the same thing as -tan(x). The tangent function is also the same thing as sin(x)/cos(x), right? So let's rewrite that tan in terms of sin and cos:
is the same as
We can now cancel out the cos(x), which leaves us only with -sin(x) remaining. So your answer is A.
3.67 teaspoons, and 1 divided by 17 is 0.05 teaspoons. (All you have to do is divide the teaspoons by X(17).
Answer:94°
Step-by-step explanation:
The sum of the interior angles of the polygon: 180°(n-2)
180°(5-2)=540°
The sum of the interior angles of the pentagon is 540°
So:
P+Q+R+S+T=540°
(4x+2)°+132°+(4x-10)°+(5x-11)°+128°=540°
4x+2+4x-10+5x-11+260=540
13x=299
x=23°
P=4x+2°=4×23°+2°=94°
Answer:
44
step-by-step explanation:
Formula
1/2*h*(sum of parallel sides(b1+b2))
Your scale on both axes are 2cm to 2units therefore the parameters are as follows
h=4
b1=9
b2=13
=44
