Answer:
38°
Step-by-step explanation:
a whole circle is equal to 360 degrees so if 52 +90= 142 the opposite side also equals 142 because they are clearly the same size. ED and AB are also the same sizes. if 360- (142+142) = 284. then you will have to divide 284 by 2. so 284÷2=76 and 76÷2=38°
hope you understand, I not that good at explaining things
also I don't know what the m means in mED
Alright, so what we can take as a given is that arcDE/2= ∠CDE=2x+20 since the arc corresponding to the angle is 2*the angle. To solve for arcDE, we multiply both sides by 2 to get 2(2x+20)=4x+40=arcDE. Since the arcs in a circle add up to 360 degrees and we only have -20+30x and arcDE, we have -20+40+4x+30x=360 using the associative property. Simplifying, we get 20+34x=340. Subtracting 20 from both sides, we get 340=34x. Next, we can divide both sides by 34 to get 10=x.
Answer:
(B) ASA
Step-by-step explanation:
we will verify each options
option-A:
we can see that there is no consecutive two angles
so, this postulates can not be true
so, this is FALSE
option-B:
We can see that
one angle and then side and another angle are equivalents
so, this is TRUE
option-C:
We can see that
one side and two angles are equivalents
so, this is FALSE
option-D:
we can see that
one side and two angles are equivalents
so, this is FALSE
