b = 2.77 m
A = 43.0°
C = 111.1°

cosine law to find b

b^2 = a^2 + c^2 -2ac \cos B \\ \\
b = \sqrt{a^2 + c^2 -2ac \cos B} \\ \\
b = \sqrt{4.33^2 + 5.92^2 - 2(4.33)(5.92) \cos 25.9} \\
b = 2.7708\ m

b = 2.7708\ m

Find angle A with sine law

\displaystyle
\frac{\sin A}{a} = \frac{\sin B}{b} \\ \\
\sin A = \frac{a \sin B}{b} \\ \\
A = \sin^{-1} \left[ \frac{a \sin B}{b}  \right] \\ \\
A = \sin^{-1} \left[ \frac{4.33 \sin 25.9}{2.7708}  \right]  \\ \\
A = 43.0467020

Find C with angles in triangle sum to 180

A + B + C = 180
C = 180 - A - B
C = 180 - 43.0467020 - 25.9
C = 111.1

By applying Segment Addition Postulate, segment FH is equal to 24 units.

<h3>What is a point?</h3>

A point can be defined as a zero dimensional geometric object and it is generally represented by a dot.

<h3>What is a line segment?</h3>

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

<u>Given the following data:</u>

  • Line segment FG = 37.
  • Segment HG = 13.

Since point H lies on line segment FG, we would apply Segment Addition Postulate to determine segment FH as follows:

FG = HG + FH

37 = 13 + FH

FH = 37 - 13

FH = 24 units.

Complete Question:

Given that line segment FG = 37 and segment HG = 13, find segment FH.

How many radians is -135°
Yuri [45]

Answer:

-3/4 pi radians

Step-by-step explanation:

<em>180° is 1 pi radian</em>

Hence, -<em>135° = -135/180 pi radians</em>

                     = -0.75 pi radians

                     = -3/4 pi radians

Which matrix represents the system of equations shown below<br> Plz help..<br> See picture
Furkat [3]
Basically

just put the coeficinets of each variable in the apropriate row

example
ax+by=c and
dx+ey=f

would go in like this
\left[\begin{array}{ccc}a&b&|c\\d&e&|f\end{array}\right]

so
3x+1=1 and
0x-1y=5

\left[\begin{array}{ccc}3&1&|1\\0&-1&|5\end{array}\right]

D is answer
