The angle m∠UVW can be found using angle of circumference rule in geometry. Therefore, m∠UVW = 67°
<h3 /><h3>Angle on a circumference</h3>
An angle at the circumference of a circle is half the angle at the centre standing on the same arc.
In other words, the angle at the centre of a circle is twice the angle at the circumference.
Therefore,
m∠UVW = 134 / 2
m∠UVW = 67 degrees

Answer:
![a=40+90n](https://tex.z-dn.net/?f=a%3D40%2B90n)
Step-by-step explanation:
Use a cofunction identity on the right hand side or left hand side...
So
.
We have the equation:
![\tan(a)=\cot(a+10)](https://tex.z-dn.net/?f=%5Ctan%28a%29%3D%5Ccot%28a%2B10%29)
Make the above replacement:
![\cot(90-a)=\cot(a+10)](https://tex.z-dn.net/?f=%5Ccot%2890-a%29%3D%5Ccot%28a%2B10%29)
Since cotangent has period 180 degrees, we can also write this as:
![\cot(90-a+180n)=\cot(a+10)](https://tex.z-dn.net/?f=%5Ccot%2890-a%2B180n%29%3D%5Ccot%28a%2B10%29)
So solving the following will give us a set of solutions for
:
![90-a+180n=a+10](https://tex.z-dn.net/?f=90-a%2B180n%3Da%2B10)
Add
on both sides:
![90+180n=2a+10](https://tex.z-dn.net/?f=90%2B180n%3D2a%2B10)
Subtract 10 on both sides:
![80+180n=2a](https://tex.z-dn.net/?f=80%2B180n%3D2a)
Divide both sides by 2:
![40+90n=a](https://tex.z-dn.net/?f=40%2B90n%3Da)
Symmetric property:
![a=40+90n](https://tex.z-dn.net/?f=a%3D40%2B90n)
32 grams = water mass + sugar mass . 100% syrup=75% water+ 25%sugar
original water content= 32*75/100=24 grams
original sugar content= 32*25/100= 8grams
total mass at 10% syrup:
8grams/total mass=10%=0.1
total mass=8/0.1=80grams
total mass of water=80grams- 8grams of sugar content= 72 grams
total mass of water added=72grams- 24grams original water content= 48grams.
answer: 48grams
Answer:
D
