Answer:
angle 1=°
Step-by-step explanation:
to find the angle of 1 you should know angle 2, what is angle 2?
angle ° and angle are symetrical so they have the same value.
now that we know that angle 2 is equal to °
then what is angle 1
if the whole line has an angle of ° and angle °.
so the equation will be :
flip the equation to find :
the angle 1 which we found in the given equation is 135
check if my answer is correct is :
my equation is correct
Answer:
-5
Step-by-step explanation:
-9+x = -14
Add 9 to each side
-9+x+9 = -14+9
x = -5
Answer:
X^2-18x+81
OR
(X-9)^2
Step-by-step explanation:
X(x-9)-9(x-9)=
x^2-9x-9x+81
X^2-18x+81
Answer:
y = 3x + 23 and
Step-by-step explanation:
The first equation is 9x - 3y = - 69 and we have to write it in slope-intercept form.
Now, 9x - 3y = - 69
⇒ 3x - y = - 23 {Dividing both sides by 3}
⇒ 3x + 23 = y
⇒ y = 3x + 23 {Interchanging the sides} (Answer)
The second equation is x - 3y = - 6 and we have to write it in slope-intercept form.
Now, x - 3y = - 6
⇒ x + 6 = 3y
⇒ 3y = x + 6 {Interchanging the sides}
⇒ {Dividing both sides by 3}
⇒ (Answer)
