Answer:
So, area of quadrilateral ABCD = (½ × AC × BE) + (½ × AC × DF) We can calculate the area of different types of quadrilaterals by using the given formula. For the quadrilateral ABCD, if we use centimeter as the unit of measurement, the unit of measure for the area will be cm2 .

Step-by-step explanation:
do 10x6x2
10x6=60
60x2=120
Answer:
b = - 2, b = 4
Step-by-step explanation:
Using the distance formula
d = 
with (x₁, y₁ ) = M(3, 1) and (x₂, y₂ ) = N(- 1, b)
d = 
= 
= 
Then
= 5 ( square both sides )
16 + (b - 1)² = 25 ( subtract 16 from both sides )
(b - 1)² = 9 ( take square root of both sides )
b - 1 = ± 
= ± 3 ( add 1 to both sides )
b = 1 ± 3
Then
b = 1 - 3 = - 2 or b = 1 + 3 = 4
Answer:
25°
Step-by-step explanation:
ACE + BCE = 180
Since sum of angles on a straight line equals 180°
(2x+2)+(5x+3)=180
7x+5=180
7x=175
x= 25°
