10% = 6
25% = 15
50% = 30
20% = 12
80 + 60 + y = 180 and if y and x are vertical angles y = x
Answer:
11.180339887498cm or 11.2cm
Step-by-step explanation:
Using pythagoras- a² + b² = c²
Therefore 5² + 10² = 125²
Root of 125 will be the answer
Answer:
so x = 20 , y = -21 , which is in quad IV
r^2= 400+441 = 841
r = √841 = 29
then cos Ø = 20/29
sec Ø = 29/20 = 1.45
