Answer:

x = 52, y = 137 degrees.

Step-by-step explanation:

x = 180 - 90 - 38

x =  52 degrees   (as there is 180 degrees in a triangle).

As they are the same side inner angles between 2 parallel lines:

x + (y - 9) = 180

52 + y - 9 = 180

y = 180 - 52 + 9

y =  137 degrees.

For each quadrilateral work out<br> The sizes of angles a b c and d <br> The value of a + b + c + d
Vika [28.1K]

Answer:

A) (i) a = 95° (180 - 85), b = 85° (180 - 95), c = 85° (180 - 95), d = 95° (180 - 85)

A) (ii) a = 103° (180 - 77), b = 77° (180 - 103), c = 103° (180 - 77), d = 77° (180 - 103)

B) (i) 95 + 85 + 85 + 95 = 360°

B (ii) 103 + 77 + 103 + 77 = 360°

Tip: Angles on a straight line add to 180°

Hope this helps!

VladimirAG [237]

Answer:

3/10 x 100 = 30.00

Step-by-step explanation:

Three tenths written as a fraction is 3/10. You can also write it as a decimal by simply dividing 3 by 10 which is 0.30.

If you multiply 0.30 with 100 you will see that you will get 30
