Hey could you help me? thank you

1 , 5 and 7 angle are 105 degree

∡1, 5, and 7 have the same measure as ∡3

Step-by-step explanation:

∡1 and ∡3 are vertical angles and congruent

∡3 and ∡7 are corresponding angles and congruent

∡5 and ∡7 are vertical angles and congruent

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
