I am pretty sure the answer is 324 or 300
Answer:
C) 405.3 ft
Step-by-step explanation:
A triangle is a polygon with three angles and three sides. Types of triangle are scalene, isosceles, equilateral, right angled triangle.
Given a triangle with angles A, B, C and the corresponding sides directly opposite to the angles as a, b, c. The sine rule states that:
![\frac{a}{sin(A)}= \frac{b}{sin(B)} =\frac{c}{sin(C)}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bsin%28A%29%7D%3D%20%5Cfrac%7Bb%7D%7Bsin%28B%29%7D%20%3D%5Cfrac%7Bc%7D%7Bsin%28C%29%7D)
In the triangle formed by point C, ship B and ship A, we have ∠A = 82°, ∠B = 78°, c = AB = 140 ft. Hence:
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
82 + 78 + ∠C = 180
∠C + 160 = 180
∠C = 20°
Using sine rule:
![\frac{c}{sin(C)}=\frac{a}{sin(A)}\\\\\frac{140}{sin(20)}=\frac{a}{sin(82)}\\\\a= \frac{140*sin (82)}{sin(20)}\\\\a=405.3\ ft](https://tex.z-dn.net/?f=%5Cfrac%7Bc%7D%7Bsin%28C%29%7D%3D%5Cfrac%7Ba%7D%7Bsin%28A%29%7D%5C%5C%5C%5C%5Cfrac%7B140%7D%7Bsin%2820%29%7D%3D%5Cfrac%7Ba%7D%7Bsin%2882%29%7D%5C%5C%5C%5Ca%3D%20%20%20%20%5Cfrac%7B140%2Asin%20%2882%29%7D%7Bsin%2820%29%7D%5C%5C%5C%5Ca%3D405.3%5C%20ft)
a = distance from Ship B to the signal fire at point C
Answer:
true
Step-by-step explanation:
Multiply the bracket by -2
2x+3y^2 -2(x-y2)
2x+3y^2-2x+2y^2
2x-2x+3y^2+2y^2- rearranging
3y^2+2y^2
5y^2
Answer: 5y^2
2/4 is equivalent to 1/16 and 1/128 if dived by 8 sections
8/8 is equivalent to 1/8 and 1/64 if dived by 8 sections
1/2 is equivalent to 1/16 and 1/128 if dived by 8 sections
3/4 is equivalent to 3/32 and 3/256 if dived by 8 sections
2/3 is equivalent to 1/12 and 1/98 if dived by 8 sections
