Find the measure of <_A. (show work if possible).

Mathematics
1 answer:
Sholpan [36]3 years ago
4 0

Answer:

<em>We </em><em>know </em><em>that </em><em>exterior </em><em>angle </em><em>of </em><em>a </em><em>triangle </em><em>is </em><em>equal </em><em>to </em><em>the </em><em>sum </em><em>of </em><em>two </em><em>opposite </em><em>interior </em><em>angle</em><em>.</em>

Step-by-step explanation:

<A = 4y

< B = 3y + 6°

<BCD = 111°

Now

<BCD = <A + <B( exterior angle of a triangle is equal to the sum of two opposite interior angle)

111° = 4y + 3y + 6°

111° - 6° = 7y

105° =7y

Therefore y = 15°

The measure of <A = 4*15°= 60°

This is stupid I know lol but I'm having a hard time remembering the difference between a histogram and a bar graph. Can someone
Y_Kistochka [10]

<u>In Bar Graphs;</u>

- Bars have equal space

- One the y-axis, we have numbers & on the x-axis, we have data which can be anything.

<u> In Histograms;</u>

- Bars are fixed

- On the y-axis, we have numbers & and on the x-axis, we have data which in continuous & will always be number.

<u>An easy way you can remember the difference is looking at the spaces of the bars. </u>

<em>A bar graph has gaps</em>

<em>A histogram has no gaps.</em>

3x=5x-9 pls help ?!!?!?!?!?!?!?!?!??!!?1/
lbvjy [14]

Answer: x = 4.5

Step-by-step explanation:

1) Reorder the terms:

3x = -9 + 5x

2) Solving

3x = -9 + 5x

3) Solving for variable 'x'.

4) Move all terms containing x to the left, all other terms to the right.

5) Add '-5x' to each side of the equation.

3x + -5x = -9 + 5x + -5x

6) Combine like terms: 3x + -5x = -2x

-2x = -9 + 5x + -5x

7) Combine like terms: 5x + -5x = 0

-2x = -9 + 0

-2x = -9

8) Divide each side by '-2'.

x = 4.5

9) Simplifying

x = 4.5
