Answer:

12.1244 or \sqrt{147}

Step-by-step explanation:

Use the Pythagorean Theorem and solve for b^2:

7^2+b^2= 14^2

Simplify:

49+b^2= 196

Subtract 49 from both sides:

49-49+b^2= 196-49

Simplifly:

b^2= 147

Unsquare both sides:

\sqrt{b} = \sqrt{147}

I need help with rhombus,rectangles and squares<br>​
AnnZ [28]

Answer:

a= 11, b= 12

Opposite angles of parallelogram are equal.

m<D = m<B

9b-2=106°

9b= 108°

b= 12°

Sum of the adjacent angles of a parallelogram = 180°

m<B+m<C = 180°

106°+7a-3=180°

7a = 180°-106°+3

7a=77°

a= 11°
