5x13 is 65...you have 65 becuase both triangles are there... 5x16 is 80... so 145... 13x16 is 208, so 353 so far. 7x16 is 112, so 465 so far. ANother 112 for the other side is 577. 12x7 is 84 times two for both sides, which is 168. 577+168 is 745. I believe that is your final area of the surface area, 745 Square feet.

What is m pls help i will mark brainly

-Dominant- [34]

Answer:

x=18

Step-by-step explanation:

Hey There!

So if you did not know all of the angles in a triangle will add up to equal 180

So we use the equation

180=2x+3x+5x

and solve for x

step 1 combine like terms

2x+3x=5x

5x+5x=10x

so now we have

180=10x

step 2 divide each side by 10

180/10=18

therefore x = 18

hope this helps and if you have any more questions feel free to ask :)
