Answer:

∠CBD = 4(4) + 52°

              = 16° + 52°

              <u>= 68°</u>

Step-by-step explanation:

Given that,

∠ABC = 8x - 10°

∠CBD = 4x + 52°

Also,

∠ABD = 90°

∠ABD = ∠ABC + ∠CBD

∠ABD (90°) = (4x + 52°) + (8x - 10°)

∠ABD (90°) = 4x + 52° + 8x - 10°

∠ABD (90°) = (4x + 8x) + (52° - 10°)

∠ABD (90°) = 12x + 42°

90° - 42° = 12x

48° = 12x

\frac{48}{12} = x

4° = x

∠CBD =  4x + 52°

∴ ∠CBD = 4(4°) + 52°

              = 16° + 52°

              = 68°

Answer:

X=34°

Y= 56°

Angle HIF are 90° when we bisectors YI 90-34

Therfore y = 56°

FGI are a triangle sum of it is 180 = 90+56

146 - 180

X= 34

PLEEEAAAAAASE HELP!<br>What is the answer to this question?<br><br>​
IrinaVladis [17]

Answer:

  • 23 units

Step-by-step explanation:

<em>Perimeter is the sum of side lengths</em>

<u>Let's find the sides first</u>

  • AB = √(-2- 2)² + (-4+1)² = 5
  • BC = (2 - (-1)) = 3
  • CD = √(-1- 2)²+(5-2)² = √18 = 3√2 = 4.24
  • DE = √(-4 -(-1))²+(2-5)²= √18 = 3√2 = 4.24
  • AE = √(-4-(-2)²+(2-(-4))²=√40= 2√10 = 6.32

<u>Perimeter is</u>

  • P = 5 + 3 + 4.24 + 4.24 + 6.32 = 22.8 ≈ 23 rounded to the nearest whole number

A bag contains 5 blue balls, 4 red balls, and 3 orange balls. If a ball is picked from the bag at random, what is the probabilit
ValentinkaMS [17]

Answer:

p =\frac{Possible}{Total}

Where possible represent the possible cases on this case 5 since we have 5 balls and the total is the size of the sample space on this case 12. And replacing we got:

p =\frac{5}{12}= 0.417

And rounded to the tenths place we got:

p=0.4

And the best answer is:

B. 0.4

Step-by-step explanation:

For this case the size of the sampel space is 5+4+3= 12 representing the total of balls used.

We select a random ball from the total and we want to find the probability of selecting a blue ball. And for this case the can use the empirical definition of probability from Laplace given by:

p =\frac{Possible}{Total}

Where possible represent the possible cases on this case 5 since we have 5 balls and the total is the size of the sample space on this case 12. And replacing we got:

p =\frac{5}{12}= 0.417

And rounded to the tenths place we got:

p=0.4

And the best answer is:

B. 0.4

If there are rectangles that all have the same perimeter, which one will have the least area? which one will have the greatest a
hichkok12 [17]
The ones that will have the least area will be the ones that are the thinnest.  That is to say, the ones with the greatest width to length (or length to width) ratios would have the smallest area. 
The ones with the greatest area would be the ones with the smallest width to length (or length to width) ratios. They would be squares.
