70) perpendicular means you take the number in from of the x and flip it and switch the sign. that number will become your slope (m).
y=mx+b. plug in slope and point
-5=(7/9)(-4)+b. multiply
-5=(-28/9)+b. add over -28/9
b= -17/9. plug b and slope into original equation
y=(7/9)x+(-17/9) get rid of frac by multi by 9
(y=(7/9)x+(-17/9))*9
9y=7x+-17. subtract over 7x
-7x+9y=-17. answer
Same goes for the rest. number 72 the perp slope will be (1/3) and for 74 the answer will be x=-5 (that is a weird case)
Answer:
3576 ÷by 38= 94
Step-by-step explanation:
I think this ans may help you
18=(2/3)x-6
+6 +6
24=(2/3)x
÷(2/3) ÷(2/3)
36=x
check it now
18=((2/3)(36))-6
18=(24)-6
18=18
that is a true statement so x must be equal to 36
x=36
Answer:
Step-by-step explanation:
By definition, the sum of the interior angles of a triangle is 180 degrees.
You can observe that the given triangle has an angle that measures 90 degrees and it also has two equal sides.This means that the other two angles are equal.
Knowing this, you can conclude that the triangle is an Isosceles Right Triangle and the other angles measure 45 degrees each.
Therefore, now you know that:
Solving for "x", you get that its value is:
And for the other angle:
Solving for "y", you get that its value is the following:
