Answer:

Step-by-step explanation:

ABC and DEF are parallel lines. So, ∠ABE and ∠BED are co interior angles.

∠ABE + ∠BED = 180   {SUM OF CO INTERIOR ANGLE IS 180}

∠ABE+ 110.2 = 180

∠ABE = 180 - 110.2

∠ABE = 69.8

Now, ABC is straight line

∠ABE + ∠EBG + ∠CBG = 180

69.8 + ∠EBG + 34.8 = 180

104.6 + ∠EBG = 180

∠EBG = 180 - 104.6

∠EBG = 75.4

Again, DEF is straight line

∠DEB + ∠BEG + ∠GEF = 180

110.2 + ∠BEG + 25.6 = 180

∠BEG + 135.8 = 180

∠BEG = 180 - 135.8

∠BEG = 44.2

In triangle BEG,

∠BEG + x  + ∠EBG = 180  { sum of all angles of triangle is 180}

44.2 + x + 75.4 = 180

x + 119.6 = 180

x = 180 - 119.6

x = 60.4

Find cos if tan = -4/3 and sin < 0
Elodia [21]
THe first thing we need to do is find the hypotenuse.  From the tangent we know that the legs of the right triangle are 3 and 4.  So this 2/3 of a special right triangle (3-4-5).  Thus the hypotenuse is 5.  The sin is defined as \frac{opposite}{hypotenuse}.  We know the opposite is 4 and hypotenuse is 5.  Thus the sin is - \frac{4}{5}

Which expression could be used to determine the reduction of -4 and 3 1/4
Setler79 [48]

Answer:

The expression that could be used is (-4)(3) + (-4)(\frac{1}{4}) ⇒ B

Step-by-step explanation:

Let us revise the distributive property:

<em>The product of a number and the sum of 2 other numbers equal to the sum of the products of the number with the other 2 numbers</em>

  • a(b + c) = ab + ac

We will use this rule to solve the question

∵ The product of -4 and 3\frac{1}{4} = -4 × 3\frac{1}{4}

→ We can right 3\frac{1}{4}  as (3 + \frac{1}{4} )

∵ 3\frac{1}{4} = (3 + \frac{1}{4} )

∴ -4 × 3\frac{1}{4} = -4(3 + \frac{1}{4} )

→ By using the rule above

∵ -4(3 + \frac{1}{4} ) = (-4)(3) + (-4)(\frac{1}{4})

∴ -4 × 3\frac{1}{4}  = (-4)(3) + (-4)(\frac{1}{4})

∴ The expression that could be used is (-4)(3) + (-4)(\frac{1}{4})

A line has a slope of -13. There is a second line that passes through points (-7,-5) and (6,-4) . Would these lines be parallel
Elza [17]
<h3>Answer: The lines are perpendicular</h3>

=================================================

Work Shown:

Use the slope formula to find the slope of the line through the two given points.

m = (y2 - y1)/(x2 - x1)

m = (-4 - (-5))/(6 - (-7))

m = (-4 + 5)/(6 + 7)

m = 1/13

The slope of the line through the two given points is 1/13.

This is not equal to -13, which was the slope of the first line, so the two lines are not parallel.

However, the two lines are perpendicular because multiplying the two slope values leads to -1

(slope1)*(slope2) = (-13)*(1/13) = -1

note: It might help to think of -13 as -13/1 to help multiply the fractions.
