Can an expert with trig me with this give extra points and brainlest

125in^2

Step-by-step explanation:

Surface area= Area of base+ 1/2ps

since it's a square the area of the base is 5 x 5 which equals 25

next we multiply the perimeter by s which is 10

it's a square so the perimeter is 5+5+5+5 = 25

so 25+1/2(250)

25+ 125

=125 in^2

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
