Answer:

C. 150

Step-by-step explanation:

The given angle and angle x are supplementary. This means that when added together they add to 180. So, to solve you can set up an algebraic equation like 180=x+30. Then, subtract 30 from both sides to get 150=x.

Hope this helped!

Answer: 4 or -4

Step-by-step explanation:

2x^2-32+32=0+32

2x^2=32

1/2*2x^2=32*1/2

x^2=16

x=4 or -4

Answer:

42

Step-by-step explanation:

The equation is, c/7 = 6

c/7= 6

By multi[lying both sides with seven,

c = 6*7

Answer:

64ft

Step-by-step explanation:

The distance between the lions and the monkeys is; 64 ft

From the given diagram, we see two triangles;

Triangle one formed by Zebras, Monkeys, lions.

Triangle two formed by tigers, elephants, lions

Now, from the given triangles we can see that they are similar and using the given dimensions, we can use proportion to find distance between the lions and the monkeys as;

52/78 = x/96

where x is the unknown distance we are looking for

We cross multiply to get;

4992 = 78x

Divide both sides by 78 to get;

x = 64 ft

Answer:

AEB =43

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

AED + AEB = 180

137+AEB = 180

AEB = 180-137

AEB =43

Answer:

[tex]\text{B. }43^{\circ}[/tex]

Step-by-step explanation:

Angles [tex]\angle AED[/tex] and [tex]\angle AEB[/tex] are supplementary, meaning they add up to 180 degrees, because they form one side of a line.

Thus, we have:

[tex]\angle AED+\angle AEB=180,\\137+\angle AEB=180,\\\angle AEB=\boxed{43^{\circ}}[/tex]

Step-by-step explanation:

2.16=216/100=54/25

check your statement.

[tex]\frac{54}{25 }[/tex] is the rational number for the decimal 2.16

A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero.

According to the given question.

We have a number 2.16

To convert the above in rational number, we convert the given number  in [tex]\frac{x}{y}[/tex] form, where x and y are positive integers.

We read 2.16 as " 2 and sixteen hundredths".

Therefore, 2.16 can be written as [tex]2\frac{16}{100}[/tex].

Now we will simplify [tex]2\frac{16}{100}[/tex].

⇒ [tex]2\frac{16}{100} =2\frac{4}{25}[/tex]

⇒ [tex]2\frac{16}{100} =\frac{54}{25}[/tex]

Hence,  [tex]\frac{54}{25 }[/tex] is the rational number for the decimal 2.16

abc = 53

Answer:

Option A

Step-by-step explanation:

Hey there!

From the given figure;

Angle ABE = 90°.

And angle ABD = [(5x+3)° +(3x+7)°]

To find : angle ABC.

Now,

Angle ABD + Angle ABE = 180° [Being linear pair].

or, 90° + [(5x+3)° +(3x+7)°]= 180°

or, (5x+3)° +(3x+7)°= 90°

or, 8x + 10° = 90°

or, 8x = 80°

Therefore, X= 10°.

Now, Angle ABC = (5x + 3)°

= (5*10+3)°

= 53°

Therefore, the measure of angle ABC is 53°.
