Answer:
TUA=123
Step-by-step explanation:
so first we find <TUS in terms of x
so 180-11x-2
178-11x
so now we can use the sum of a triangle's angles which is always 180 to find the angles in triangle TUS
178-11x+5x+10+58=180
178-6x=112
take 178 from both sides
-6x=-66
x=11
so we can do 11x11+2=TUA
TUA=123
Answer:
1386cm squared
Step-by-step explanation: first find the diameter.
132=pi x diameter
132=22/7xd
multiply both sides by 22/7 and you'll get 42cm
then find the area by doing this.
22/7x21x21 which gives you 1386cm squared.
the 21 is the radius.
Answer:
22 cm
Step-by-step explanation:
radius is 3 1/2 cm, which is 3.5 in decimal form
the circumference comes out to be 21.99, which is rounded to 22.
