Answer:
The answer to your question is: the second option is correct
Step-by-step explanation:
m∠1 = 180 - 66 - 37
= 77°
m∠2 = 180 - 41 - (180 - 77)
= 180 - 41 - 103
= 36°
m∠3 = 180 - 47 - (180 - 77)
= 180 - 47 - 103
= 30°
Answer:
x = 5
Step-by-step explanation:
x² - 5x = 0
(x² - 5x) /x = 0/x
x²/x - 5x/x = 0
x - 5 = 0
x = 5
Check:
x² - 5x = 0
5² - 5*5 = 0
25 - 25 = 0

Step-by-step explanation:
<em>Compatible numbers</em> are numbers that are easy to use in mental arithmetic.
Martin gave away ⅖ of 7 lb of grapes, so the amount he gave away was
⅖ × 7 lb
⅖ is close to ²/₄ (½), and it is easy to take half of something mentally.
Half of 7 is about 3, so Martin gave away about 3 lb of grapes (the exact answer is 2.8 lb).
