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!
Siince 2nd equation is already equal a, subsitute b-2 for a in the other equation
b-2-3b=28
-2-2b=28
add 2 to both sides
-2b=30
divide both sides by -2
b=-15
sub back
a=b-2
a=-15-2
a=-17
(a,b)
(-17,-15)
3rd choice
Answer:
Y=1.88x
Step-by-step explanation:
x1=2 x2=3, y1=3.76 y2=5.64
(2, 3.76) (3, 5.64)
m(slope) =5.64-3.76/3-2
m=1.88
y-3.76=1.88(x-2)
y-3.76=1.88x-3.76
Y=1.88x
