Answer:

x=54º

y=63º

Step-by-step explanation:

Let the other angle in the triangle be zº.

Because the measure of a line is 180º, zº=180º-117º=63º.

Because the triangle is isosceles yº=zº=63º.

The sum of the measure of the angles in a triangle is 180º. So, 63º+63º+xº=180º.

126º+xº=180º

xº=54º

Y is directly proportional to x when y=30, x=6

rosijanka [135]

Answer:

a) y = 5x

b) y = 60

Step-by-step explanation:

Since, y is directly proportional to x when y=30, x=6

$\therefore \: y \: \alpha \: \: x \\ \therefore \: y = kx ...(1) \\ plug \: y = 30 \: and \: x = 6 \: in \: eq \: (1)\\ 30 = k \times 6 \\ k = \frac{30}{6} \\ k = 5 \\ plug \: k = 5 \: in \: (1) \\ y = 5x....(2) \: (required \: equation) \\ plug \: x = 12 \: in \: eq \: (2) \\ y = 5 \times 12 \\ \huge \red{ \boxed{y = 60}}$
