Which expressions can be used to find m∠ABC? Check all that apply.

valina [46]

Answer:

$\cos^{-1}(\frac{6.3}{9.8})$

$\sin^{-1}(\frac{7.5}{9.8})$

Step-by-step explanation:

Recall the mnemonics SOH-CAH-TOA

The sine ratio is the length of the opposite side expressed over the hypotenuse.

$\sin m\angle ABC=\frac{7.5}{9.8}$

Take the sine inverse of both sides to get;

$m\angle ABC=\sin^{-1}(\frac{7.5}{9.8})$

The cosine ratio is the length of the adjacent side expressed over the hypotenuse.

$\cos m\angle ABC=\frac{6.3}{9.8}$

Take the cosine inverse of both sides to get;

$m\angle ABC=\cos^{-1}(\frac{6.3}{9.8})$

Aunt bess uses 3 cups of oatmeal to bake 6 dozen cookies how many cups of oatmeal will she need to bake 18 dozen cookies

Andrei [34K]

There are several important information's already given in the question. Based on those information's the answer to the question can be easily deduced.
Number of cups of Oatmeal
required by Aunt Bess for making 6 dozen cookies = 3
Then
Number of cups of oatmeal
required by Aunt Bess for making 1 dozen cookies = (3/6)
= 1/2
So
Number of cups of oatmeal
required by Aunt Bess for making 18 dozen cookies = (1/2) * 18
= 9 cups
So Aunt Bess will require 9 cups of oatmeal for baking 18 dozen cookies. I hope the procedure is clear enough for you to undestand.
