Answer : 60 degrees
Explanation: All triangles's angles add up to 180. Since all angles are equal, you can divide 180 by 3. 180/3 is 60
Use the quadratic formula -b+/-√b^2 -4(ac) / 2a
-4 +/- √(4^2 - 4(1*10) / (2*1)
X = -2 +/- i√6
The answer is 30
2 * 15 = 30
5 * 6 = 30
30 is between 24 and 34
25% because 21 is a quarter of 84. And 21 times 4= 84, so 21 is 25% of 84.
Answer:
Step-by-step explanation:
(in X is 400) (in division is 0.000625) (in + its agin 400) ( and in minus is -40)
hope this help you if not i tried. :)
