Step-by-step explanation:

Given

See attachment

Required

The constant of proportionality

Select two points on the graph

(x_1,y_1) = (0,0)

(x_2,y_2) = (4,3)

So, the constant of proportionality (k) is:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{3-0}{4-0}

m = \frac{3}{4}

Answer:

x = 20°

y = 70°

Step-by-step explanation:

the angle adjacent to the 40° angle must be 140° because the two angles form a straight line (which contains 180°)

in the isosceles triangle with the 'x', that means the other two angles must be equal and are (180-140) ÷ 2, which equals 20°

to find 'y', consider the larger right triangle with angles of 90° and 20°; angle y must equal 180 - (90 + 20) = 70°
