Answer:
<u>Use sine for this:</u>
- sin 30° = x/19
- x = 19 sin 30°
- x = 19(1/2)
- x = 9.5
Answer:
A straight angle measures 180 degrees.
So if one of those angles is 40 degrees, the other angle is 180-40, or 140 degrees. Answer C
Step-by-step explanation:
Answer:
see the explanation
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of arc EH
Remember that the measure of the complete circle is equal to 360 degrees
so
Remember that
----> by central angle
----> by central angle
---> by central angle
substitute the given values
step 2
Which arc is congruent to Arc E H?
we know that
therefore
arc EH is congruent with arc EFG
or
arc EH is congruent with minor arc GE
STEP 1:
Tally up the total number of batches.
= 3 batches + 4 batches
= 7 batches
STEP 2:
Multiply the total number of batches by the amount of butter used in one batch (which is 1/4 cup).
= 7 batches * 1/4 cup per batch
= 7 * 1/4
= (7*1)/4
= 7/4
= 1 3/4 cup of butter
Beth used 1 3/4 cup of butter to make a total of 7 batches of cookies.
Hope this helps! :)
