Answer:
x° = 78°
Step-by-step explanation:
x° is the measure of external angle BHC of triangle BHD. As such, its measure is the sum of the opposite interior angles at B and D:
47° + 31° = x° = 78°
Answer:
and
Step-by-step explanation:
Since we have given that
Old length of rectangular garden feet
The Old breadth of rectangular garden feet
If feet are added to all the sides.
So, the New length of a rectangular garden is given by
The New breadth of a rectangular garden is given by .
Hence, the new dimensions of the garden are
You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
