The Colonel spots a campfire at a bearing N 71 ∘ E from his current position. Sarge, who is positioned 235 feet due east of the

Salsk061 [2.6K]

Answer:

$X=85.123m$

$Y=184.88m$

Step-by-step explanation:

From the question we are told that:

Campfire Bearing from Colonel $x=N 71 \textdegree E$

Distance b/w Colonel and Sarge $Z=235feet$

Campfire Bearing from Sarge $y=N 45 \textdegree E$

Generally the angles x' and y' are solved

$x'=90 \textdegree-71 \textdegree$

$x'=19 \textdegree$

$y'=90 \textdegree-45 \textdegree$

$y'=45 \textdegree$

Generally the angle z' is solved

Sum of angles of a triangle is 180

Therefore

$z'=180 \textdegree-(19+45) \textdegree$

$z'=116 \textdegree$

Generally the sine rule equation for for all distances is mathematically given by

$\frac{Z}{sinz'}=\frac{X}{sinx'}=\frac{Y}{siny}$

Generally the the distance b/w the Colonel and the campfire X is mathematically given as

$\frac{235}{sin116}=\frac{X}{sinx'}$

$\frac{235}{sin116}=\frac{X}{sin19}$

$X=85.123m$

Generally the the distance b/w Sarge and the campfire X is mathematically given as

$\frac{235}{sin116}=\frac{Y}{siny}$

$\frac{235}{sin116}=\frac{Y}{sin45}$

$Y=184.88m$

Circle 1 is center at (-4,5) and has a radius of 2 centimeters. Circle 2 is centered at (2,1) and has a radius of 6 centimeters.

Bumek [7]

Let's denote the circle with small radius circle A and the circle with bigger radius as circle B. In order to perform the translation, you should follow these steps

1) Draw a vector from point A to B

2)Dilate circle A to circle B. It means translating mapping circle A to circle B.

3)By this way, we can claim that circles A and B are similar.

And the similarity ratio is $\frac{ r_{2} }{ r_{1} } = \frac{6}{2} =3$

Naya [18.7K]

151 ounces, or 9 pounds 7 ounces

16 ounces = 1 pound
131 ounces = 8.1875 pounds
After 4 weeks Omar gains 20 ounces, which is 1.25 pounds.
8.1875 + 1.25 = 9.4375 pounds

I need help with congruence and similarity problem. ( picture below)

adell [148]

Answer:

x = 9, y = 4 and z = 6.67

Step-by-step explanation:

Since both the polygons are similar, by the property of similarity corresponding sides of the polygons will be proportional.

Therefore, $\frac{x}{6}=\frac{12}{8}$
