Answer:

Step-by-step explanation:

Because the only step is to subtract 9 from both sides and then you get x=12

Answer:

there is no one step equation becuz

x+9 = 21

take 9 to the other side becos both are same variables then

21-9 = x

hence x= 12

next x=11 question can't be answered becuz this is not a complete question

2x+9 = 21

21-9 = 2x

12=2x

-----

hwnce 12/2 = 6 therefore x= 6

Type SSS, SAS, ASA, SAA, or HL to justify why the two larger triangles are congruent.

kipiarov [429]

Answer:

SAS

Step-by-step explanation:

It doesnt show the hypotenuse so its no HL

It doesnt show 2 angles so its not SAA or ASA

It doesnt show three sides so its not SSS

The little line indicates that the sides are congruent. They both have a right angle and the bottom lines are right on top of each other so its SAS
