3. I believe the answer is C & A, arrange the boards so that the diagonals bisects and  are perpendicular. A rhombus is a Quadrilateral with all its sides equal to each other. The diagonals of  a rhombus are perpendicular to each other and bisects each other.

4.The corresponding pairs of base angles of a trapezoid add up to 180 degrees, (they are supplementary), While all the angles (the four angles add up to 360 degrees)
Therefore; in this case the two angles are equal
    hence, 19x + 8 = 11x+16    solving for x
                           x = 1
substituting x in either of the expression
The angle = 27 °
 
5. The diagonals of a rhombus bisects each other at right angles; the are perpendicular,
hence,
m∠1= 10x = 90
                 x = 9

m∠2 = x + y =90
but x = 9,
thus, y = 81

m∠3 = 5z= 90
              z =18

10. A kite is a Quadrilateral with two equal sides and the other two sides equal. 
thus, y-4 = 5x+2   and x +22 = 3x +10
solving for x
x+22 = 3x +10
   2x = 12
     x = 6
y-4 = 5x +2
  y-4 = 5(6) +2
      y = 36.

11.a. RHOM is a Quadrilateral with four equal sides
     b. The four sides RH, OH, OM, and RM are equal, They are all congruent
     c   HM and HM is the diagonal, which forms the corresponding sides of triangle MRH and triangle MOH 
      d.  Triangle MRH and triangle MOH are congruent, SSS, and similar to each other.

In circle O, what is mArc A E?
posledela

Answer:

Option (3). 120° will be the answer.

Step-by-step explanation:

By using the theorem of secants intersecting externally,

Measure of angle formed by two secants, from a point outside the circle is half the difference of the measures of the intercepted arcs.

m∠C = \frac{1}{2}(m\widehat{AE}-m\widehat{BD})

36° = \frac{1}{2}(m\widehat{AE}-48)

72° = m\widehat{AE}-48°

m\widehat{AE} = 72 + 48

m\widehat{AE} = 120°

Therefore, Option (3) is the answer.

Kelly has a ribbon that is 60 inches long she cuts at 40% of ribbon for an art project while working on the project she decided
Amiraneli [1.4K]

Answer:

8.4 inches

Step-by-step explanation:

To find the amount of inches, multiply the length by the percent. A percent is 40% but can also be written as a decimal conversion as 0.4. Then 40% of 60 inches is 0.4(60)= 24 inches.

However, she didn't use all 24 inches. She used 35%. This converts to 0.35 and then multiply for 0.35(24) = 8.4 inches.

She used 8.4 inches.

HELP WILL MARK BRAINLIEST!!!!!!!
zlopas [31]

Answer and Step-by-step explanation:

4 hours on Monday, so subtract 4 from 16.

We get 12.

So now it says twice as many on Saturday as on Thursday

So two numbers that add up to 12, but one number is twice the other number, would be 4.

4 times 2 is 8, and 4 + 8 is 12. 12 + 4 = 16

8 is the answer.

Kyle works 8 hours on Saturday.

Since 8 is twice the amount of 4, and 8 + 4 + 4 equals 16.

What is 5 to the 25th power?
nordsb [41]
5^25 = 5 * 25^12 = 5 * 625^6 = 1220703125. Making an even power and squaring the value to divide the power by 2 reduces the time and just enter it in a calculator.
