Pentagon DEFGH was translated 2 units left and 4 units up to create pentagon D’E’F’G’H’. Which rule describes this transformation? A.(x, y)--->(x-2,y-4)
B.(x, y)--->(x+4,y+2)
C.(x, y)--->(x-2,y+4)
D.(x, y)--->(x-4,y+2)

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
