Answer:
x = 67.5 degrees
Step-by-step explanation:
A circles' angles add upto 360 degrees and one of the angle is 90 degrees.
=> x+3x+90 = 360 degrees
=> 4x+90 = 360
=> 4x = 360-90
=> 4x = 270
Dividing both sides by 4
=> x = 67.5 degrees
So, the measure of <x is 67.5 degrees.
Answer:
A = 58 degrees
b = 51.9
c = 48.5
Step-by-step explanation:
To find A we simply just need to remember that all triangles add up to 180 degrees and we are already given two angles of the triangle so....
![57 + 65=122](https://tex.z-dn.net/?f=57%20%2B%2065%3D122)
![122+58=180](https://tex.z-dn.net/?f=122%2B58%3D180)
![A=58](https://tex.z-dn.net/?f=A%3D58)
To find sides b and c we use the law of sines since we now know the angle of each side.
![a=48](https://tex.z-dn.net/?f=a%3D48)
![b=48\times\frac{sin65}{sin57} =51.87](https://tex.z-dn.net/?f=b%3D48%5Ctimes%5Cfrac%7Bsin65%7D%7Bsin57%7D%20%3D51.87)

![c=48\times\frac{sin58}{sin57} =48.54](https://tex.z-dn.net/?f=c%3D48%5Ctimes%5Cfrac%7Bsin58%7D%7Bsin57%7D%20%3D48.54)
![48.54](https://tex.z-dn.net/?f=48.54)

![c=48.5](https://tex.z-dn.net/?f=c%3D48.5)
