Well seems like the question wants you to give an equation which should be something like x-3
Answer:
Step-by-step explanation:
because <u>c</u> is shorter than<u> a</u> we know C is a smaller angle than A
so the first choice is out.
use the law of cosines to find b
= 
=1681+400-1326.787871
= 754.21219
b= 
b= 27.46292
so the last choice looks good
Answer:
They are vertical angles
Step-by-step explanation:
They are congruent because they are across from each other over a straight line. They are also called vertical angles.
i cant tell what is says so ill just give you the formulas
perimiter = Length x 2 + Width x 2
Area = Length x Width.
Ok so what's the question?
