Let's move all to one side:
6r+7-13-7r=0
and re-arrange to have similar terms together:
6r-7r +7-13=0
let's add up what we can:
-1r-6=0
we can move the -6 to the other side and multiply both sides by -1 and we get:
r=-6 This is the<em> solution. </em>
Answer:
tanC = 3/4
Step-by-step explanation:
by Pythagoras theorem first find the line DE =
+
=
-> DE=27
then we know that tanθ=opposite/adjacent
so, 27/36 =tanC
simplified: tanC = 3/4

Answer:
Nope
Step-by-step explanation:
No, it is not possible; Possible explanation: Four sides connected at these angles cannot form a closed figure. The sum of the angles in a quadrilateral is 360°. Possible quadrilaterals include a rhombus, a parallelogram, a trapezoid, and an unclassified quadrilateral.
