Answer:

x=3/4

Step-by-step explanation:

Set up an equation:

1/6+x=1 2/3-x

1/6+x=5/3-x

1/6+x=10/6-x

2x=9/6

2x=3/2

4x=3

x=3/4

Check:

common denominator of 12

2/12+9/12=11/12 AND 20/12-9/12=11/12

Please help me with this

Area of the trapezoid:
$\frac{12.8 + 4.2}{2} (4.9) = 41.65 cm^2$

Area of the rectangle:
4.2 x 3.1 = 13.02 cm^2

Area of each quarter circle:
$\frac{ \pi (3.1)^{2} }{4} = 7.54 cm^2$

We have two quarter circles:
7.54 + 7.54 = 15.08

41.65 + 13.02 + 15.08 = 69.75 cm^2

Step-by-step explanation:

Given that,

BC = 8

Ac = 15

We can find AB using the pythagoas theorem.

$AB=\sqrt{AC^2+BC^2}\\\\=\sqrt{15^2+8^2}\\\\AB=17$
