Finding angles , please help

Mathematics
1 answer:
jek_recluse [69]2 years ago
8 0

Answer:

  • m∠C = 43.6°, m∠B = 107.4°, b = 51.2

Step-by-step explanation:

<u>Use the law of sines:</u>

  • a / sin ∠A = c / sin ∠C
  • 26 / sin 29° = 37 / sin ∠C
  • sin ∠C = 37 sin 29° / 26
  • sin ∠C = 0.6899
  • m∠C = arcsin 0.6899
  • m∠C = 43.6°

<u>Find the missing angle:</u>

  • m∠B = 180° - 29° - 43.6° = 107.4° (rounded)

<u>Use the law of sines to find the length of b:</u>

  • a / sin ∠A = b / sin ∠B
  • 26 / sin 29° = b / sin 107.4°
  • b = 26 sin 107.4° / sin 29°
  • b = 51.2 units (rounded)

2. Write the slope-intercept form of the equation of the line described.
yanalaym [24]

Answer:

y = -x + 1

Step-by-step explanation:

We're putting it into the form y=mx+b where m is the slope, and b is the y-intercept.

When two lines are parallel, they have the same slope, so the slope is going to be -1.

New equation: y = -x + b.

Now, you know that (4, -3) is a solution so you can plug in x = 4 and y = -3, then see what value of b make the equation true.

-3 = -4 + b

add 4 to both sides

1 = b

This means that the equation is y = -x + 1

Kay [80]

Answer:

f^-1 (9) = 7 equals f = 9/7

Step-by-step explanation:

f^-1 x 9 = 7, f ≠ 0

1/f x 9 = 7

9/f = 7

9 = 7f

7f = 9
