C 120’ is the answer

Answer:

C. 120 deg

Step-by-step explanation:

All sides of a rhombus are congruent.

That means that triangle ADC is an isosceles triangle with AD = CD, so angles DAE and DCE are congruent.

m<DAE + m<DCE + m<ADC = 180

30 + 30 + m<ADC = 180

m<ADC = 120

Opposite angles of a rhombus are congruent, so

m<ABC = m<ADC = 120

Alex wants to arrange chairs in such a way that the number of chairs in a row is equal to the number of columns. He has ordered
PIT_PIT [208]

Answer:

84

59

Step-by-step explanation:

In other to have the same number of chayes in both rows and columns ;

If the Number of chairs per row = x ; then number of chairs per column = x

Then the total number of chairs needed = x * x = x²

Hence, if there are 5100 chairs ;

Number of chairs needed more ;

Take the square root of 5100 ;the round to the next whole number :

B.) For number of chairs to be removed ;

Take the square root of 5100 and round down to the whole number.

Hence,

A.) = √5100 = 71.414 = 72

72² - 5100 = 84

B.) 5100 = 71.414 = 71

5100 - 71² =

To find $9,567 rounded to the nearest hundred you must first find the hundreds place which is where 5 is then according to the number behind it you either round up or you keep 5 the same since the number behind 5 is 6 you round 5 up one which brings 5 to 6 now everything behind your new number is turned to 0. so your new amount would be $9,600

What is the measure of Angle z?
denis-greek [22]

Answer:

Angle z makes a 180° angle when added to the angle of 124° in the first image, because they are on the same side of a straight line. Just subtract 124 from 180. =56 For the second picture, angle m will be the same as angle z because of the properties involved.

A function assigns the values. The graph can be plotted as shown below.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given the function, g(x) = -3(1/2)ˣ, therefore, the value of g(x) can be written as,

g(x) = -3(1/2)ˣ

g(-2) = -3(1/2)² = -0.75

g(-1) = -3(1/2)¹ = -1.5

g(0) = -3(1/2)⁰ = -3

g(1) = -3(1/2)¹ = -1.5

Hence, the graph can be plotted as shown below.
