Tan x degrees = 31

To find X use arctan.

x = arctan(31)

x = 88.15

Can someone help me with these I don’t understand at all

cupoosta [38]

Answer:

#1: ????

#2: $\frac{3}{4}$ x $15$

#3: $\frac{7}{8}$ ÷ $\frac{3}{4}$

Step-by-step explanation:

For #2:

$\frac{3}{4}$ x $15$ .

It's that because there are 3/4 cups of honey for one cake. To use for 15 cakes, you would have to multiply it by 15.

For #3:

$\frac{7}{8}$ ÷ $\frac{3}{4}$ .

It's that because the baker has 7/8 cups of honey. It takes 3/4 cups of honey for one cake. So you have to divide it by 3/4 cups in order to find out how many cakes.

Hope this helped! <3
