Answer:
45 degrees 
Step-by-step explanation:
AOB = 140°
and an the angle bisector(OC) is a line which will divide AOB into 2 equal angles 
which is 140÷2= 70
and if AOD = 25 then COD= 70-25
= 45 degrees

Answer:
The value of  is -16.
 is -16.
Step-by-step explanation:
We need to evaluate  for x = -1, y = 5 and let us assume that z = 1
 for x = -1, y = 5 and let us assume that z = 1
It can be simply done by putting the values of x,y and z in the given expression.

We know that the value of 4² = 16
So,

So, the value of  is -16.
 is -16.
 
        
             
        
        
        
Answer:
4 11/16 m²
Step-by-step explanation:
The formula for the area of a rectangle = Length × Width
From the question:
Length = 1 1/4 m
Width = 3 3/4m
Area of the rectangle =
1 1/4 m × 3 3/4 m
= 5/4 m × 15/4 m
= 75/16 m²
= 4 11/16 m²
Area of the rectangle = 4 11/16 m²
