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.
Answer: Y= 67
Step-by-step explanation:
The equation says;
Y= 15x + 7
When x=4
We have Y= 15(4)+7 by substituting the value of x for the equation. So, we have
Y=60+7
Y= 67
Answer:
7 Weeks
Step-by-step explanation:
If she starts off with 40 reps for the first week, and she adds 6 reps a week, until she gets to 82 reps a week, then it would be<em> 40 + 6 x answer = 82</em>. Now, there are a couple ways you can do this, but the easiest but not shortest way is to do it one by one.
so, <em>40+6x1= 46</em>
<em>40+6x2= 52</em>
<em>40+6x3= 58</em>, and so on and so forth, until you get to <em>40+6x7</em><u>,</u> which equals 82, therefore giving you the answer of 7, but the way quicker way is to take the total (82) and subtract the number of reps she starts out with (40), then divide that number by the amount that it increases each week (6), so:
(82-40)÷6, which will also give you the answer of 7, or 7 weeks.
I think it is (10,-7) but lmk otherwise
