We use 2 different rules here:
1) sum of angles in a triangle is equal to 180 degrees
2) when a triangle side is a diameter of the circle, then angle opposite to diameter is equal to 90 degrees.
so from 2) we know that B= 90
then from first one:
sum of angles = 180 = 90 + (3x + 6) + x = 96 + 4x
so 180 - 96 = 4x
so x = 84/4
x = 21
so answer is
A= 3x+ 6 = 63 + 6 = 69
B = 90
C = 21
10 times 50 is 500
So your answer is 50.
Answer:
C
Step-by-step explanation:
1. press 9
2. then the exponet key
3. then press 6
4. finally press the equal sign (=)
2x+9<0
This is asking for numbers below 0
x>-12
This is asking for numbers above - 12
So the numbers which would fit in both of these rules would be:
-11, -10, -9, -8, -7, -6, -5
Any numbers above or below these wouldn't fit into any of the inequalities
