b. have symptoms that can be treated with therapy and medication
c. involve less anxiety than most normal people experience
d. are not affected by a healthy diet and regular exercise

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°

folds are formed when heat and pressure is applied to the rock. the higher the temperature, the more pliable rocks become. folds are more likely to occur when the deformation caused by the compression is applied slowly. faults are defined as the displacement of rock that were once connected along a fault line.
