Answer:
a. 235°
b. 146.03 km
c. 105 km
d. 193 km
Step-by-step explanation:
a. The bearing of E from A is given as 55°. The bearing in the opposite direction, from E to A, is this angle with 180° added:
bearing of A from E = 55° +180° = 235°
__
b. The internal angle at E is the difference between the external angle at C and the internal angle at A:
∠E = 134° -55° = 79°
The law of sines tells you ...
CE/sin(∠A) = CA/sin(∠E)
CE = CA(sin(∠A)/sin(∠E)) = (175 km)·sin(55°)/sin(79°) ≈ 146.03 km
CE ≈ 146 km
__
c. The internal angle at C is the supplement of the external angle, so is ...
∠C = 180° -134° = 46°
The distance PE is opposite that angle, and CE is the hypotenuse of the right triangle CPE. The sine trig relation is helpful here:
Sin = Opposite/Hypotenuse
sin(46°) = PE/CE
PE = CE·sin(46°) = 146.03 km·sin(46°) ≈ 105.05 km
PE ≈ 105 km
__
d. DE can be found from the law of cosines:
DE² = DC² +CE² -2·DC·CE·cos(134°)
DE² = 60² +146.03² -2(60)(146.03)cos(134°) ≈ 37099.43
DE = √37099.43 ≈ 192.6 . . . km
DE is about 193 km
Answer: 4.9
Step-by-step explanation: delta math
Answer:
d = 81
Step-by-step explanation:
Solve for d:
36 = (4 d)/9
Hint: | Reverse the equality in 36 = (4 d)/9 in order to isolate d to the left hand side.
36 = (4 d)/9 is equivalent to (4 d)/9 = 36:
(4 d)/9 = 36
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (4 d)/9 = 36 by 9/4:
(9×4 d)/(4×9) = 9/4×36
Hint: | Express 9/4×4/9 as a single fraction.
9/4×4/9 = (9×4)/(4×9):
(9×4)/(4×9) d = 9/4×36
Hint: | Express 9/4×36 as a single fraction.
9/4×36 = (9×36)/4:
(9×4 d)/(4×9) = (9×36)/4
Hint: | Cancel common terms in the numerator and denominator of (9×4 d)/(4×9).
(9×4 d)/(4×9) = (4×9)/(4×9)×d = d:
d = (9×36)/4
Hint: | In (9×36)/4, divide 36 in the numerator by 4 in the denominator.
36/4 = (4×9)/4 = 9:
d = 9×9
Hint: | Multiply 9 and 9 together.
9×9 = 81:
Answer: d = 81
