Suppose a triangle has two sides of length 42 and 35, and that the angle between these two sides is 120 degrees. What is the len
FrozenT [24]

Answer:

Option D

Step-by-step explanation:

The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other and the given angle is the included angle. This means that the angle is formed by the intersection of the two lines. Therefore, cosine rule will be used to calculate the length of b. The cosine rule is:

b^2 = a^2 + c^2 - 2*a*c*cos(B).

The question specifies that a=42, B=120°, and c=35. Plugging in the values:

b^2 = 42^2 + 35^2 - 2(42)(35)*cos(120°).

Simplifying gives:

b^2 = 4459.

Taking square root on the both sides gives b = 66.78 (rounded to the two decimal places).

This means that the length of the third side is 66.78 units!!!

In ΔNLM, if m∠M=(4x-4)°, m∠L=(3x+12)°, and m∠N=(6x+3)°, what is x?
GarryVolchara [31]

Answer:

  x = 13

Step-by-step explanation:

The sum of angle measures in a triangle is 180°.

  m∠M + m∠L + m∠N = 180°

  (4x-4)° + (3x+12)° + (6x+3)° = 180°

  13x +11 = 180 . . . . . . collect terms, divide by °

  13x = 169 . . . . . . . . . subtract 11

  x = 13 . . . . . . . . . . . . . divide by 13

How do I slove 96-2r=6r-112
Ad libitum [116K]
<span>96-2r=6r-112
Add 2r to both sides
96=8r-112
Add 112 to both sides
208=8r
Divide 8 on both sides
Final Answer: 26=r</span>
