Answer:
Sum of all angles is 720°
x=105
∠H=110°
∠I=100°
∠K=135°
Step-by-step explanation:
The sum of all inetrior angles is 720°
So,
140+105+130+(x+5)+(x-5)+(x+30)=720
375+3x+30=720
405+3x=720
3x=720-405
3x=315
∴x=105
∠H=x+5
∠H=105+5
∴∠H=110°
∠I=x-5
∠I=105-5
∴∠I=100°
∠K=x+30
∠K=105+30
∴∠K=135°
<span>Hello : let
A(5,-4) B(-1,8)
the slope is : (YB - YA)/(XB -XA)
(8+4)/(-1-5) =-2
an equation is : y=ax+b a is a slope</span>
y = -2x +b
the line through point A(5,-4) :
-4= -2(5)+b<span>
<span>b = 6
the equation is : y =-2x+6</span></span>
Answer:
A) 
Step-by-step explanation:
To isolate
, we need to divide both sides by
. Therefore, the answer is
.
