Answer:
Radius
Step-by-step explanation:
180-90=3x
90=3x
X=30
90+x+y=180
90+30+y=180
120+y=180
Y=60
Answer:
A
Step-by-step explanation:
1) first there are a few rules we need to know:
a) the sum of any two sides of a triangle is always larger than the 3rd side
b) the difference between any two sides of a triangle is always smaller than the 3rd side;
hence,
3+4=7
4-3=1
triangle 3,4,5 follows all the rules,
triangle 13,2,11:
11+2=13
the sum of any two sides must always be GREATER than the 3rd side-so this is not an option
triangle 10,4,5
5+4=9
9<10
not an option
I would maybe say a Rhombus. They have two likes of symmetry ^^ Hope this helps!
