Answer:

<CBD =75 degrees.

Step-by-step explanation:

I'm assuming that you want to know the value of <DBC

When a ray has the fixed end on a line, that ray will cut the line into 2 angles that total 180o.

In simpler language <ABD + <CBD = 180

<ABD = 105 degrees which is a given,
105 + <CBD = 180 Subtract 105 from both sides.
105-105 + <CBD = 180 - 105
<CBD = 75 Degrees Answer

Answer:

DBC = 75

Step-by-step explanation:

ABD and DBC are supplementary angles. They add to 180 degrees.

ABD + DBC = 180

105 + DBC = 180

Subtract 105 from each side

105-105 + DBC = 180-105

DBC = 75

(4x)(3z+y)+2x(3y+2z)=axz +bxy. Determine the values of a, b, and c

olganol [36]

Answer:

a = 16

b = 10

In the equation from the question there's no value that you can determine for c.

Step-by-step explanation:

(4x)(3z+y)+2x(3y+2z)=axz+bxy
12xz+4xy+6xy+4xz
16xz+10xy

What are the measures of Angles d, e, and f? Show your work and explain your answers. (10 points)

Sholpan [36]

Answer:

Part A - Angle d is 29º

Part B - Angle e is 61º

Part C - Angle f is 95º

Part D - the box represents a 90º angle

Step-by-step explanation:

Angle d is 29º because of the vertical angles theorem

Angle e is 61º because if you take into account that it tells you one of the angles is 90º, you'll add d, which is 29º, to that in order to get 119. Then you'll subtract 119 from 180, as all the angles in a triangle must have a sum of 180º degrees. The result should be 61º

Although it looks rather acute, f should be 95 degrees because it's a supplementary angle with 85º, meaning you subtract 85 from 180

The box in the triangle is just a symbol indicating a 90º angle

a recent survey show that the average man will spend 141,288 hours sleeping, 85,725 hours working, 81681 hours watching televisi

Lady bird [3.3K]

Answer:

12.5% of his time working.

Step-by-step explanation:

This is (85725 * 100)/( 141288+85725+81681+9945+1662+363447)

= 8572500 / 683748

= 12.5%.
