To find <ABC, the first thing you would need to do is to find angle DBA and the value of x
As <DBE is a right angle, <DBE is on the same straight line as well,meaning that it would be 90° , a right angle as well.
It also mean that the total sum of the angles unknown would be 90°
To find x,we need to set up an equation:
(2x+14)+ (x+7) = 90
3x+21 = 90
3x = 69
x = 23
Thus,<ABC would be
(23)+7
=30°
Hope it helps!
Solve it like a normal equation, but with < instead of =
9k - 2 < 3k + 10
-3k -3k
_____________
6k - 2 < 10
+2 < +2
_____________
6k < 12
÷6 ÷6
_____________
k < 2 is your final answer :)
Answer:
D.) 8x^2+11x-9
Step-by-step explanation:
5x^2 -(-3x^2) =8x^2
7x -(-4x) =11x
-4 -5 =-9
Hope it helps
Because 0 + 27 is 27 and 10 + 17 is 27 as well
