Answer:
Step-by-step explanation:
Remember that the sum of the interior angles of a triangle always equal 180. Therefore:
Let's subtract 102 from both sides. This yields:
Now, notice the that both ∠1 and ∠Y have exactly one arc mark.
Arc-marks denote congruence. Therefore, ∠1 and ∠Y are congruent to each other. In other words:
So, we can substitute ∠Y for ∠1 for our equation. This yields:
Combine like terms:
Divide both sides by 2. So, the measure of our angle is:
And we're done!

Answer:
336 ft^2
Step-by-step explanation:
All you have to do is find the area of each face, and add them up.
Firstly lets starts with the identical triangles.
There are two of them, and the area of a triangle is b*h/2
So the area is 6*8/2 , which is 24, and since their are two of them, we add another 24, and we get 48 so far.
Since all the other sides are rectangles, we can just multiply the given lengths and add them up.
So, we have
12x10, which is 120,
12x8, which is 96, and
12x6, which is 72.
Now add all of them up.
48+120+96+72 which is 336
Your answer is 336 ft^2
