The two triangles in the diagram are similar. there are 2 possible values of x.

i have managed to work out what x is but i’m not sure what to put in terms of the assumptions.

x = 2

Step-by-step explanation:

Given data: The two triangles in the diagram are similar.

AB = 10 cm, AC = x cm, AE = 15 cm, AD = 3 cm

By similar triangles property,  

Do cross multiply

⇒ 10 × 3 = 15 × x

⇒ 30 = 15x

⇒ 30 ÷15 = 15x ÷ 15(By division property of equality)

⇒ x = 2

Hence, the possible value for x is 2.

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 : )
