The measure of angle Y is 45, and the measure of angle Z is 70z What is the measure of angle W

If it is referring to a triangle then the answer is 65

Step-by-step explanation:

Each triangle has three angle that have a sum of 180 degrees. if the first 2 equal 115 then the third will equal 65.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
