First find the area of the triangle.

\sf A=\dfrac{1}{2}bh

\sf A=\dfrac{1}{2}(6)(12)

\sf A=36cm^2

ABCE is a parallelogram, this means that the area of triangle ABE is equal to the area of triangle EBC. The are of the entire trapezoid is 180 square centimeters, we already found the area of the triangle, so that leaves us with:

\sf 180-36=144

So the area of the entire parallelogram must be 144 square centimeters. So each half of the parallelogram must be equal to:

\sf 144\div 2=\boxed{\sf 72cm^2}

How would i find h please help!!
antiseptic1488 [7]

Answer:

35

Step-by-step explanation:

So the triangle who posses the angle with measurement k=35 is an isosceles.  I know this because there are two congruent legs.  Those 2 congruent legs tell us the angles opposite of them are all congruent.

So we know one equation to solve is:

x+x+35=180 where x is the base angle in the left triangle picture.

Combine like terms:

2x+35=180

Subtract 35 on both sides:

2x=180-35

Simplify:

2x=145

Divide both sides by 2:

x=72.5

So one of the base angles of the left isosceles triangle is vertical with with another angle in the right.  This triangle on the right is also isosceles.

So we know that 72.5+72.5+h=180.

Combine like terms:

145+h=180

Subtract 145 on both sides:

h=180-145

Simplify:

h=35

kogti [31]
<span>In a triangle the sum of two sides is always greater than the third side.

</span><span>A:12,9,21
</span><span>12+9 = 21
21 = 21  </span>⇒  no

<span>B:7,6,12
</span>7+6 = 13
13 > 12  ⇒  yes

<span>C:3,8,14
</span>3+8 = 11
11 < 14  ⇒  no

<span>D:23,13,37
</span>23+13= 36
