to support use of natural gas
to promote recycling programs
to promote energy conservation
to support use of public transportation

i believe it is option 1, 2, and 5? sorry if i am off

Explanation:

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°

d will be ur answer

to mark sum 1 brainliest there has to be 2 answer at least
