Answer: 40°
<u>Step-by-step explanation:</u>
There are 4 pink angles (labeled as "a") and each are the same measure.
There are 4 green angles (labeled as "b") and each measure 50°.
A circle is 360°
4a + 4b = 360
4a + 4(50) = 360
4a + 200 = 360
4a = 160
a = 40
Answers are 2,3,4. This is due to opposite angles and angle pairs due to a transversal with a parallel

Answer:
The solution of the system of equation in coordinate form is (2, 0)
Step-by-step explanation:
The given equation are;
2·x - y = 4....................(1)
5·x + 2·y = 10..............(2)
Multiplying equation (1) by 2 and subtract it from equation (2) gives;
5·x + 2·y - 2 × (2·x - y) = 10 - 2×4
5·x - 4·x + 2·y - 2·y = 2
x = 2
From equation (1), we have 2·x - y = 4, when x = 2, we get;
2×2 - y = 4
y = 2×2 -4 = 0
y = 0
Therefore;
The solution of the system of equation in coordinate form is (2, 0).
Y intercept is -2 (the y intercept is found by seeing where the line passes the y axis)
slope is 5/2 or 2.5
equation is: y = 2.5x -2
