Which of the following is an example of a roadblock to achieving a goal? a. too much optimism b. short-term goals c. constructive critisism d. fear of change

fear of change, you can have too much optimism or confudence short term goals are a must have and do i really need to say any thing about constructive critisism D is the way to go.

angle a = 40.6°

step-by-step explanation:

for any right angle triangle we know the pythagoras theorem reveals

hypotenuse² = height²+base²

by this formula we will calculate the length of hypotenuse

h² = 6²+7²

⇒ h =√36+49 = √85 = 9.22

now from the given triangle sin a = height/ hypotenuse

                                                sin a = 6/9.22 = 0.651

therefore

so angle a = 40.6°
