Answer:
x=59 y= 81 z= 99
Step-by-step explanation:
z=
180-(57+24)=99
y=180-99=81
x= 40+81=121
180-121=59
Answer:
v = 8
Step-by-step explanation:
8v+5=13+7v
Subtract 5 from 13
8v=8+7v
Subtract 7v from 8v
Final answer: v = 8
There is a trig identity called the sum of 2 angles for sin its<span>
sin(a+b)=sin(a)cos(b)+cos(a)(sin(b)
</span>
You will need to use it. So in your question split the 4x in 2 equal parts 2x and 2x
<span>
</span><span>sin(4x)=sin(2x+2x)
</span>Now using the expansion above you will get
<span>sin(2x+2x)=sin(2x)×cos(2x)+cos(2x)×sin(2x)
</span>And it will simplify to
<span><span>2sin(2x)cos(2x)
I hope this helps you! Good luck :)</span></span>

$116.02 interest will be earned in 9 months
Step-by-step explanation:
The formula for simple interest is given by:
Here
P is the initial amount
r is the interest
t is the time measured in years
Given
P = $2475
r = 6.25% = 
t = 9 months
Converting time into year by dividing by 12
Putting the values in the formula
Rounding off to nearest hundredth
I = $116.02
Hence,
$116.02 interest will be earned in 9 months
