Given the triangle ABC
AD=6 CE=3 CB=5
What should be the length of AB so that the area of a triangle ABC is compatible with the rest of the data in the drawing?
Given the triangle ABC
AD=6 CE=3 CB=5
What should be the length of AB so that the area of a triangle ABC is compatible with the rest of the data in the drawing?
In which part of the drawing was an error made?
so that the area of the triangle is 24 cm²? Which data should be in place of the error?
In triangle ABC given in cm:
AC=10 BD=12 AB=20 EC=5
Which of the data must be changed so that the area of a triangle ABC is 60 cm²?
Given the triangle ABC
AD=6 CE=3 CB=5
What should be the length of AB so that the area of a triangle ABC is compatible with the rest of the data in the drawing?
Given that AD is perpendicular to CB
We can establish that AD is the height of the triangle ADB
Hence the formula for the area of triangle ABC=
We insert the existing data into the formula:
Due to the fact that CE is also a height, we can calculate the area of triangle ABC as follows:
Since we found the area of triangle ABC, we will insert the data into the formula:
We then multiply across:
Lastly we divide both sides by 3:
10 cm
In which part of the drawing was an error made?
so that the area of the triangle is 24 cm²? Which data should be in place of the error?
EG=4.8
In triangle ABC given in cm:
AC=10 BD=12 AB=20 EC=5
Which of the data must be changed so that the area of a triangle ABC is 60 cm²?
Answer B or answer C is correct
