#1:
A)
you need to know where a vertex goes on a isosceles triangle...
I attached a picture that explains it.....
you also want to label triangle.... XYZ
I put a picture on of how you should of labeled the triangle...
B)
so we need to find Measure for each angle.... REMEMBER: A triangle angles needs to = 180.
so your equations will need to be equal to 180.
4x+4+2x+2+7x-8=180
so we combine liked terms
4x+2x+7x=13x
4+2-8=-2
13x-2=180
+2 +2
13x=182
/13 /13
x=14
now you plug in X
4(14)+4= 60
2(14)+2= 30
7(14)-8= 90
now you want to check you answers so add them up to see if your answers equal 180...
60+30+90=180
to be continued.... i do second question on a second answer since i dont want pictures to get mixed up
Answer:
A and E
Step-by-step explanation:
A is true because two congruent chords have the two corresponding (in this specific case small) arc that are congruent
B we haven’t enough information to say it, same of C and D
E is true because CED and BFC are congruent because they have three corresponding side that are congruent
Answer: No
Step-by-step explanation:
I believe there would only be one describing both if they were parallel lines, but they are going two different directions in this graph. Correct me if I am wrong!
