Which triangle is similar to abc? pls answer asap ;w;

The triangle which is similar to ABC is the top right triangle (refer to image below).

Step-by-step explanation:

We know that angle B = 61°.

To find angle A we need to subtract 126 from 180:

                180 - 126 = 54°        

                            A = 54°

Now to find angle C we just have to add angles A and B and subtract the answer from 180. Because the three angles of a triangle add up to 180.

                54 + 61 = 115°

               180 - 115 = 65°

                          C = 65°

The angles of ABC are 54°, 61°, and 65°. The only triangle that shows the correct angles is the top right.

b) well because you get well

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
