12.28 = 12 and 28 hundredths so its 12
Hope I helped!
Answer:
<EFC = 90 degrees
Step-by-step explanation:
<EFA = <AFD = 45 degrees
<EFC = 180 - 45 - 45 = 180 - 90 = 90
Answer:
x = -3
Step-by-step explanation:
2x = -6
You want to get x on it's own, so divide both sides by the coefficient, 2.
2x/2 = -6/2
x = -3
We already discussed the first triangle which should be HL :D!
For the second one it should be ASA (Question 17)
ASA states i<span>f two angles and the </span>included side<span> of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
As for question 16 the question is cut off but assuming it is the same thing it will most likely be SSS since it states i</span><span>f three sides of one triangle are congruent to three sides of another triangle, then the triangles are considered congruent.
For question 18 or what is above it I cannot be too sure...
AS for the one that is 18 or below it with just SSS and SAS. I would say it would be SAS since it states that i</span><span>f two sides and the </span>included angle<span> of one triangle are congruent to the corresponding parts of another triangle, then they are congruent.</span><span>

Answer:
subtract 2 from both sides
Step-by-step explanation:
2+|4x-3|=7
|4x-3|+2=7
step 1:add -2 to both sides/subtract 2 from both sides (they are the same)
Step 2: Solve Absolute Value.
|4x−3|=5
We know either4x−3=5 or 4x−3=−5
4x−3=5(Possibility 1)
4x−3+3=5+3(Add 3 to both sides)
4x=8
4x
/4=8/4
(Divide both sides by 4)
x=2
4x−3=−5 (Possibility 2)
4x−3+3=−5+3 (Add 3 to both sides)
4x=−2
4x
/4
=
−2
/4
(Divide both sides by 4)
x=
−1
/2
Answer:
x=2 or x=
−1
/2
