Answer:
-4, -3
Step-by-step explanation:
greg score = x
kara score = 3/4x-1
x + 3/4x-1 = 153
1 3/4x -1 = 153
1 3/4x = 154
x = 154 / 1 3/4 = 88
gregs score was 88
kara s score was 153 -88 = 65
Is the answer probably going to be a or c? hope that helped
Look up "sum of interior angles of a polygon" on Google. There you will find a formula for predicting the number of interior angles that a given polygone will have. This formula is <span> (n - 2) × 180°, where n represents the number of sides of the polygon in question. Count these sides. Substitute your value for n into this formula. The interior angles of your polygon add up to the result of evaluating this formula. Call this "sum." Then:
"sum" = (the one unknown interior angle) + (the sum of the given (known)) interior angles).</span>
