You need the Law of Cosines here, since you only have 1 angle measure.  If you had 2 you could use the Law of Sines, but nevertheless, we'll get there.  The Law of Cosines for our particular set of info looks like this: x^2=65^2+41^2-2(65)(41)cos(35).  Simplifying a bit we get x^2=4225+1681-4366.080396 and x^2=1539.9196.  Taking the square root of that and considering the principle root only, x = 39.2, second choice down.

\bf 15x^2-24x+9\div 3x-3\implies \cfrac{15x^2-24x+9}{3x-3}\implies \cfrac{\underline{3}(5x^2-8x+3)}{\underline{3}(x-1)}
\\\\\\
\cfrac{5x^2-8x+3}{x-1}\implies \cfrac{(5x-3)\underline{(x-1)}}{\underline{(x-1)}}\implies 5x-3

Answer:

<h2>120 square meters</h2>

Step-by-step explanation:

To find the SA of 2 Triangles, we will use the formula... B x H, and the Base and Height is going to be the dimensions of just 1 triangle, but it's going to give the answer for 2 triangles, in this shape, we have 2 triangles.

SA = B x H

= 6 x 4

= 24

24 square meters for both of the triangles

Now, let's find the SA of the rectangle on the bottom...

SA = L x W

= 6 x 6

= 36

36 square meters for 1 of the 3 rectangular parts, the one on the bottom

Now, lets find the SA of the 2 rectangles on the top. We'll use the dimensions of 1 rectangle and find the answer for 2 answers by using the formula...

SA = L x W x 2

= 6 x 5 x 2

= 30 x 2

= 60

60 square meters for the 2 rectangles on the top.

Now, we have to add all of our answers.

24 + 36 + 60 = 120 square meters

<h2>Hence, the SA (surface area) of this shape is 120 square meters.</h2>
