4. Triangle XYZ is graphed on a coordinate grid with vertices at X(-2,5), Y(-1,-7), and Z(2,-4). Triangle XYZ is dilated by a scale factor of u with the origin as the center of dilation to create triangle X'Y'Z'. Which ordered pair represents the coordinates of the vertex Y'? A. (-1 + U, -7 + u)
(Yellow Hearts)
B. (-1 -u, -7 - u) (Red Hearts)
C. (-1u, -7u) (Pink Hearts)
D. (-7,-) (Green Hearts)​

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
