Two bird watchers position themselves at point A (the beach) and point C (the shed) which are 111 feet apart. The both spot a ra

o-na [289]

Answer:120 ft

Step-by-step explanation:

Given

Beach(A) and Shed (C) is $111$ feet apart

If Two bird watchers set then at A and C and observe a bird at $94^{\circ}$ and $46^{\circ}$

Using Trigonometric relation

$\tan 86=\frac{h}{x}---1$

$\tan 46=\frac{h}{111+x}---2$

from 1 and 2

$x\tan 86=(111+x)\tan 46$

$x=8.66\ ft\approx 9\ ft$

Therefore bird is $120\ ft$ from point C

What is the answer to -7(7m-4)=77

il63 [147K]

<span>-7(7m-4)=77
Use distributive property(Multiply -7 by 7m and -4)
-49m + 28= 77
Subtract 28 from both sides
-49m= 49
Divide -49 on both sides so that the only thing remaining on the left side is the variable m.
Final Answer: m = -1</span>

The coordinates of the vertices of A DEF are D(-4,1), E(3. – 1), and F(-1, – 4)

liq [111]

Answer:

ΔDEF is not a right triangle because no two sides are perpendicular.

Step-by-step explanation:

The coordinates of the vertices of ΔDEF are given to be D(-4,1), E(3,-1) and F(-1,-4).

Now length of DE is given by $\sqrt{(-4-3)^{2}+(1-(-1))^{2} } =\sqrt{53}$ units

length of EF is given by $\sqrt{(3-(-1))^{2}+(-1-(-4))^{2} }=\sqrt{25}$ units

and length of FD is given by $\sqrt{(-4-(-1))^{2}+(1-(-4))^{2} } =\sqrt{34}$ units.

Therefore, 53 ≠ 25+34

Hence, the length of the sides does not support the Pythagoras theorem.

So, ΔDEF is not a right triangle because no two sides are perpendicular. (Answer)
