The slope of the line is -10.5.
{x-(-3/4)}^2=3^2
(x+3/4)^2=9
{(4x+3)/4}^2=9
(4x+3)^2/16=9
(4x+3)^2=9*16
16x^2+2*4x*3+3^2=144
16x^2+24x+9=144
16x^2+24x+9-144=0
16x^2+24x-135=0
Answer:
x ≈ 4.1 cm
Step-by-step explanation:
The side (z) opposite the 42° triangle can be found from the relation ...
z/(3.6 cm) = tan(42°)
z = (3.6 cm)·tan(42°) ≈ 3.2415 cm
The relationship between z and x is ...
z/x = cos(38°)
x = z/cos(38°) ≈ 4.1135 cm
x ≈ 4.1 cm
P= perimeter. x= # of inches. 4=number of sides in a square
P= 4x
so, P= 13.4 x 4. Therefore, the perimeter is 53.6 inches.
Out of the three options the first one is the right answer with the given numbers <span />
