So put all the x together then the y then the regular numbers. So this translates to
5x - 6x +9x -y + 8.
That would be 8x - y + 8
Answer:
x = 5
Step-by-step explanation:
The sum of the side lengths shown is ...
(2x) + (3x +2) + (4x +1) = 9x +3
That is the perimeter of the inscribed triangle. That triangle is similar to triangle ABC by a scale factor of 1:2, so the perimeter of ΔABC is ...
2(9x +3) = 96 = 18x +6
90 = 18x . . . . subtract 6
90/18 = x = 5 . . . . . divide by the coefficient of x
Answer:
x=
Step-by-step explanation:
First, we need to solve the angle inside the triangle. That would be 55+40+angle measure=180
angle measure=85°
Now that we know that, we can solve for x by setting 85-3x-18 equal to 180° because these two values form a linear pair which is 180°.
Let's use some simple algebra to solve for x:
85-3x-18=180
67-3x=180
-3x=113
x= or about -37.67
Hope this helps!! :)
Well a right triangle is made up of a 180 degree angle and take away 90 degrees because the right angle is already there so the answer is that PQR is a right triangle since the other two angles = 90 when added hope this helps i did alot of research:)
