Answer:
57% to the nearest whole number
Step-by-step explanation:
That is (80/139.3) * 100
= 0.5743 * 100
= 57.43%.
If i is a normal variable: then it is -30i^2 - i*j + 20j^2
If i is the constant i, then it is 20j^2 -i*j + 30
This is a quadrilateral, so the sum of interior angle measures, like a rectangle or square ( who’s interior angle measures are4 x 90) —— is 360
So ...
E + 89 + 130 + 90 = 360
E + 309 = 360
- 309 - 309
E = 51 degrees
