You convert the 20% in to .20 then you do 70 times .20 and move the decimal 2 spots back an then the answer is 14.

Answer:

CDJ= 34

Step-by-step explanation:

We know that ADJ = 90 degrees

ADK = 180 degrees and JDK equals 90 degrees so ADJ must equal 90 degrees

ADJ = ADC+CDJ

ADJ =4x+ 3x-8

Since ADJ = 90 degrees

90 = 4x+3x-8

Combine like terms

90 = 7x-8

Add 8 to each side

90+8 = 7x-8+8

98 = 7x

Divide each side by 7

98/7 = 7x/7

14 =x

We want to know CDJ

CDJ = 3x-8

CDJ = 3(14) -8

CDJ = 42-8

CDJ= 34

Find the perimeter of quadrilateral ABCD. Round to the nearest tenth.

guajiro [1.7K]

Answer:

Perimeter = 13.5 units

Step-by-step explanation:

Coordinates of A → (1, 2)

Coordinates of B → (2, 5)

Coordinates of C → (5, 7)

Coordinates of D → (4, 4)

Length of AB = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1}})^2}$

= $\sqrt{(2-1)^2+(5-2)^2}=\sqrt{10}$ units

Length of BC = $\sqrt{(5-2)^2+(7-5)^2}$

= $\sqrt{13}$ units

Length of CD = $\sqrt{(5-4)^2+(7-4)^2}=\sqrt{10}$ units

Length of AC = $\sqrt{(4-1)^2+(4-2)^2}=\sqrt{13}$ units

Perimeter of the quadrilateral = $2(\sqrt{10}+\sqrt{13})$

= 2(3.16 + 3.61)

= 13.54

≈ 13.5 units

Perimeter of the quadrilateral ABCD is 13.5 units
