Hello,

\widehat{A}=180^o-24.4^o-103.6^o=52^o\\\\\dfrac{sin(24.4^o)}{37.3} =\dfrac{sin(103.6^o)}{c} \\\\\\c=87.760246\approx{87.8}\\\\\\\dfrac{sin(52^o)}{a} =\dfrac{sin(24.4^o)}{37.3} \\\\\\a=71.1510189...\approx{71.2}\\

A point p is on the bearing of 335 from a point Q find the bearing of Q from P
RoseWind [281]

Answer:

The bearing of Q from P is 155°.

Step-by-step explanation:

In the attached photo,

Fig 1. gives details about the question and fig 2. gives the answer to the question.

From fig 1:

b° + 335° = 360° (sum of angle at a point)

b° + 335° = 360°

Collect like terms

b° = 360° – 335°

b° = 25°

a° + b° = 180° (sum of angle in a straight line)

a° + b° = 180°

b° = 25°

a° + 25° = 180°

Collect like terms

a° = 180° – 25°

a° = 155°

a° gives the bearing of Q from P.

Therefore, the bearing of Q from P is 155°.

Fig 2 on the attached photo shows the the bearing of Q from P.

Angela uses a scanner to make a reduced-size (smaller) copy of a rectangular photo that is 8 inches long and 4 inches wide. The
svet-max [94.6K]

Answer:

The new width = 2 inches

Step-by-step explanation:

Original dimensions of the rectangular photo:

Length : width = 8 inches : 4 inches

Reduced dimensions of the rectangular photo:

Let

x = the new width

Length : width = 4 inches : x inches

Equate both dimensions to get the value of x

Length : width

8 inches : 4 inches = 4 inches : x inches

8 / 4 = 4 / x

Cross product

8 * x = 4 * 4

8x = 16

x = 16/8

x = 2 inches

The new width = 2 inches
