Answer: 52

Step-by-step explanation:

You can see that it is a right angle and 90-38=52. Then because they are vertical angles they equal each other meaning that IGJ is 52 degrees

Answer:

x=11

Step-by-step explanation:

Using the Exterior Angle Theorem. . .

(3x+8) + (2x+9) = (8x-16)

Solve to get x = 11

What is the slope of this line −4x+7=2y−3

harina [27]

First, change this equation to y-intercept form:
-4x+7=2y-3
2y = -4x+10
y= -2x + 5
The slope is -2, which is the coefficient for x in y-intercept form.

Is y = 6x direct, inverse or neither?

Morgarella [4.7K]

Direct variation always has the relationship y=kx. Indirect inverse variation always has the relationship y=k/x.

In this case y=kx, where k=6, so this is a direct variation.

What is the value of x?

Andrew [12]

<h3>Answer:</h3>

$x = 25$

<h3>Solution:</h3>

$\frac{40}{40+24} = \frac{x}{x +15} \\ \frac{40}{64} = \frac{x}{x +15} \\ \frac{5}{8} = \frac{x}{x +15} \\ 5(x +15) = 8x \\ 5x +75 = 8x \\ 75 = 3x \\ 25 = x$

<h3>Explanation:</h3>

Angle BDR is congruent to angle QDC because they share common angles. Angles BRD and QCD are congruent because lines BR and QC are <em>parallel</em> and line DR intersecting them creates <em>two corresponding angles</em>, BRD and QCD. Because of the reasons I mentioned, Triangles DBR and DQC are similar by Angle Angle Similarity Postulate and because these two triangles are similar they must share the same scaling factor of corresponding sides (example: $\frac{DQ}{DB}\\$ ). So $\frac{DQ}{DB} = \frac{DC}{DR}\\$ .
