The trigonometric function that can be used to find the value of x is 12 / tan ( 25 ) . The correct values of a and b will be 12 and 25 resp . .
 Given :
 A right angle triangle , one angle = 25 ° and side opposite given angle = 12 units .
Trigonometric Formula for Tan θ
tan θ = perpendicular / base , tan θ = ( sin θ / cos θ ) , tan θ = ( 1 / cot θ ) .
where θ = 25 , perpendicular = 12 , base = x .
Substituting values in above first formula ,
tan 25 = 12 / x 
Therefore , x = 12 / tan ( 25 ) .
Hence , a = 12 and b = 25 .

Answer:
Measure of arc ZWX is <u>230°.</u>
Step-by-step explanation:
Given:
arc WX = 50°
Now 
The diameter divide a circle into two equal parts
so

Since WZ is diameter of the circle.
 
 
substituting in above equation we get

Hence Measure of arc ZWX is <u>230°.</u>
