Answer:

11.4 units

Step-by-step explanation:

b/sinB = a/sinA

b/sin(42) = 17/sin(88)

b = sin(42) × 17/sin(88)

b = 11.38215401

Answer:

Step-by-step explanation:

Use the law of sines.

\frac{sin A}{a} = \frac{sin B}{b} \\

Plug values in.

\frac{sin88}{17} = \frac{sin42}{b}\\

Cross multiply.

bsin88 = 17sin42\\b = 11.38

Hope that helps.

Write a system of linear equations for the graph below.​
sp2606 [1]
<h2>Answer:</h2>

We need to determine the equation of both lines first.

  • Line 1: <em>y = -2x + 3</em>
  • Line 2: <em>y = -1/3x - 2</em>

Now that we know the equations, we can set up a system of equations for this graph where both equations are in standard form.

Line 1:

y = -2x + 3\\\\2x + y = 3

Line 2:

y = -\frac{1}{3}x - 2\\\\\frac{1}{3}x + y = -2

<em>Final answer:</em>

2x + y = 3\\\frac{1}{3}x + y = -2

1. If RU = 16, UT = 20, and SR = 16, what is the perimeter of SUT?
nlexa [21]

Answer:

72

Step-by-step explanation:

If SR and RU have the same length, a right angle, and a shared side, we know that they are congruent triangles using SAS (Side Angle Side). Our equation to find the perimeter would be SR + RU + UT + TS or 16 + 16 + 20 + 20(using our knowledge of the congruent triangles) = 72.
