Supplemenary angles because angle 2 is 90 degrees and angle 1 is 180 degrees
Answer:
310
Step-by-step explanation:
A circle is 360 degrees
50 +x = 360
x = 360-50
x = 310
Step-By-Step Explanation:
1. 20.95 x 1 = 20.95
2. 119.5 x 2 = 239
3. 8.75 x 5 = 77.5
4. 24.25 x 7 = 169.75
5. 52.3 x 3 = 156.9
6. 0.4
7. 0.4
8. 0.4
9. 0.7
10. 0.5

Angle sum of a triangle = 180°
Therefore:
Equation No. 1 -
2 ( 2x - 4 ) + 5y = 180°
2 ( 2x - 4 ) + 5 [ ( 2x - 4 ) / 5 ] = 180
4x - 8 + [ 5 ( 2x - 4 ) / 5 ] = 180
4x - 8 + 2x - 4 = 180
4x + 2x = 180 + 8 + 4
6x = 192
x = 192 / 6
x = 32°
Equation No. 2 -
5y = 2x - 4
y = ( 2x - 4 ) / 5
ANSWER:
x = 32°
