The radicand of 2 is irrational
Answer:
26
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees, use this and set up an equation;
x + ( 4x -5 ) + 55 = 180
Simplify
x + ( 4x - 5 ) + 55 = 180
5x + 50 = 180
Inverse operations;
5x + 50 = 180
-50 - 50
5x = 130
/5 /5
x = 26

< ABE and < CBD.
Adjacent angles are two angles that have a common vertex and a common side but do not overlap.
Answer:
z = 1/2 or 0.5
Step-by-step explanation:
13 - 3z = 15z + 4
+3z +3z
13 = 18z + 4
-4 -4
9 = 18z
z = 9/18
z = 1/2 or 0.5
