<h3>Answer:</h3>

a) no solutions

b) B = 49.8° or 130.2°

<h3>Explanation:</h3>

a) By the law of sines, ...

... sin(B)/b = sin(A)/a

... sin(B) = b·sin(A)/a = (11/9)·sin(61°) = 1.069 . . . . . not realizable

there is no solution

b) As before, ...

... sin(B) = (28/25)·sin(43°) ≈ 0.763838...

... B = arcsin(0.763838...) ≈ 49.80°

The side length b is longer than the side length a, so there will be two solutions. The other angle for B is the supplement to this one:

... B = 180° -49.8° = 130.2°

Write a linear function f with f(−10)=4 and f(−2)=4.
Orlov [11]

f(-10) = 4

f(-2) = 4

Since y is constant while x isnt we just dont need to put x

f(x) = 4

The sides of a triangle measure 3√6 2√24 7√54 what is the perimeter of the triangle
Sliva [168]

Answer:

Step-by-step explanation:

3*√6 + 2√24 + 7√54= P

3√6 + 2√2*2*6 + 7√3*3*6

3√6 + 2*2√6+7*3√6

3√6 + 4√6 + 21√6

28√6 = the perimeter.

X= <br> Y=<br> Find the values of X and Y
Art [367]
<h3><u>Answer:</u></h3>
  • x = 50°
  • y = 65°
<h3><u>Step-by-step explanation:</u></h3>

<u>We can clearly see that the triangle is an isosceles triangle. This also means that y must equal to 180 - 115. Let's solve.</u>

  • => x + y + 180 - 115 = 180
  • => x + y + 65 = 180

<u>Since 180 - 115 equals 65, this means that </u><u>y = 65.</u>

  • => x + 65 + 65 = 180
  • => x + 130 = 180
  • => x = 180 - 130
  • => x = 50
<h3><u>Conclusion:</u></h3>

<u>Therefore, our answers are:</u>

  • x = 50°
  • y = 65°

Hoped this helped.
