Answer:
x = 23°
Step-by-step explanation:
- The figure given below is an irregular polygon with 7 sides
- The polygon is therefore an irregular heptagon.
We are required to determine the value of x
- We know the sum interior angles of a polygon is given by;
- Sum of interior angles = (n-2) 180 , where n is the number of sides
Therefore, in this case;
Sum of interior angles = (7 - 2 ) 180
= 900°
Hence;
7x° + 2x° + 8x° + 60° + 10x° + 8x° + 35° = 900°
35x° + 95° = 900°
35x° = 805°
x = 23°
Thus, the value of x is 23°

Answer:
ZD = 10
Step-by-step explanation:
In a parallelogram
- Every two opposite sides are parallel
- Every two opposite sides are equal
- Every two opposite angles are equal
- Every two adjacent angles are supplementary
- The two diagonals bisect each other (meet each other at their midpoint)
Let us solve the question
∵ ABCD is a parallelogram
∵ AC and DB are its diagonals
→ By using the 5th property above
∴ AC and BD bisect each other
∵ AC ∩ BD at point Z
→ That means Z is the midpoint of them
∴ Z is the midpoint of BD
→ That means Z divides BD into 2 equal parts BZ and ZD
∴ BZ = ZD
∵ BZ = 10
∴ ZD = 10
Answer:
c
Step-by-step explanation:
substitute the values of x and y in each equation
take choice c
y = 3(-2)+ 4
-6+4 = -2 = y
so c is the answer
