Answer:
x = 45.3°
Step-by-step explanation:
The distant between the first bird and the bird watcher is opposite to the reference angle, x° = 32 ft
The hypotenuse is the distance between the second bird and the bird watcher = 45 ft.
Therefore,




Answer:
Step-by-step explanation:
What he did at the end of the given equations is solve for x in x + 8y= 21
x = 21 - 8y Substitute that result in the top equation.
<u><em>7(21 - 8y) + 5y = 14 </em></u> is the correct step To continue Remove the brackets
147 - 56y + 5y = 14 Combine
147 - 51y = 14 Add 51y to both sides.
147 = 51y + 14 Subtract 14 from both sides.
133 = 51y divide by 51
y = 2.61 rounded.
The incorrect step is <em><u>underlined and italicized.</u></em>
I would have to guess a bar graph, because it would calculate and compare the amounts to each person, but that would just be my guess.
