Answer:

x = 5, <DEG = 112, <GEF = 68, <DEF = 180

Step-by-step explanation:

<DEG + <GEF = 180

23x - 3 + 12x + 8 = 180

35x + 5 = 180

Subtract 5 from both sides

35x = 175

Divide each side by 35

x = 5

Plug x = 5 into <DEG

23x - 3

23(5) - 3

<DEG = 112

Plug x = 5 into <GEF

12x + 8

12(5) + 8

<GEF = 68

<DEF is a straight angle so it automatically is 180

Answer:

$x=134.05m$

Step-by-step explanation:

From the question we are told that:

Slant Height of Kite $h_s=175$

Angle $\theta=40 \textdegree$

Since Emma,The Kite and Andrew forms a right angle triangle

Generally the equation for distance between Andrew from Emma is mathematically given by

$x=h_scos\theta$

$x=175cos40$

$x=134.05m$

A jeweler is making a triangular pendant. He has two sides of length 23 mm and 31 mm. What are the

denis-greek [22]

Answer:

38.60mm

Step-by-step explanation:

Step one:

Given data

We are given that the dimension of the triangles are length 23 mm and 31 mm

Let us assume that the triangle is a right angle triangle

Step two:

Applying the Pythagoras theorem we can find the third as

$z^2= x^2+y^2\\\\z^2= 31^2+23^2\\\\z^2= 961+529\\\\z^2= 1490\\\\$

square both sides

z= √ 1490

z= 38.60mm

Hence a possible dimension of the third side is 38.60mm
