This is the concept of trigonometry, the value of the measure of the supplementary angles can be obtained as follows;
supplementary angles sum up to 180 degrees, thus;
(2x+3)+(3x+2)=180
2x+3+3x+2=180
collecting like terms we get:
2x+3x+3+2=180
5x+5=180
5x=180-5
5x=175
thus;
x=175/5
x=35
Thus the value of the angles will be:
3x+2
=35*3+2
=107
the size of the other angle will be:
180-107
=73
Answer:
Step-by-step explanation:
The answer is going to be 1,462.5$. And that's because 9.75% of 500$=48.75$. So we just multiply 48.75 by 30 which signifies 30 years. So the workout gives us the solution; 48.75*30=1,462.5.
Answer:
27lbs
Step-by-step explanation:
$132 divide by 22lbs = 6 dollars per pound
then divide 162 dollars by 6 to see how many pounds you can get = 27
Answer:
sin 3x - cos x = 3 (sin x)(cos x)(cos x) -(sin x)(sin x)(sin x) -cos x
Step-by-step explanation:
sin 3x - cos x
This uses Trig Identities.
sin 3x = sin (x + x + x) = sin (x+x)*cos x + cos (x + x) sin x
= 2sinxcosx * cos x + [ (cos x)(cos x) -(sin x)(sin x) ] (sin x)
sin 3x - cos x = 2sinxcosx * cos x + [ (cos x)(cos x) -(sin x)(sin x) ] (sin x) -cos x
sin 3x - cos x = 2sinxcosx * cos x + sinx (cos x)(cos x) -(sin x)(sin x)(sin x) -cos x
sin 3x - cos x = 3 sinx cosx * cos x -(sin x)(sin x)(sin x) -cos x
sin 3x - cos x = 3 (sin x)(cos x)(cos x) -(sin x)(sin x)(sin x) -cos x
