Answer:
a:
1. ABC = 60°
2. BCA = 90°
3. CAB = 30°
b:
XVR = WVS = 125°
RVS = 55°
RST = VSU = 110°
RSV = UST= 70°
TUS = 39°
Step-by-step explanation:
a:
According this is a Right Triangle ( BCA = 90°) and the sum angles of a triangle is 180° :
90+5x+9x+6=180
14x=84
x=6
Then we have : ABC = 9(6)+6 =60
CBA = 5(6)=30
b :
Given that the size of the opposite angles to a vertex are equal and the sum of the interior angles of a triangle is 180 degrees, the size of all angles can be easily found.
Repeating; it's .252525252525252525252525
You do 65+90=155
then 180-155=25 to get the angle next to w
w=155

Answer:
length = 12 cm | width = 5 cm
Step-by-step explanation:
You already know the width is 5 cm. So now just divide 5 from 60 to get the length of 12 cm.
