Mathematics
1 answer:
ryzh [129]2 years ago
5 0

Answer:

x = 60

Step-by-step explanation:

The sum of exterior angles in a rectangle is equal to 360

so to find the value of x we need to use all given values and write an equation:

x + 2x + x + 2x = 360 add like terms

6x = 360 divide both sides by 6

x = 60

Which graph represents the function f(x)=4*3^x (f times x equals 4 times three to the power of x)
pychu [463]

Answer:

The answer to your question is the first graph in the second line.

Step-by-step explanation:

First graph in the first line: it shows a positive graph that intercepts the y-axis in 5, then this graph is not the correct answer.

Second graph in the first line: it shows a negative graph, this option is incorrect, we look for a positive graph.

First graph in the second line: is correct because is a positive graph and intercpts the y-axis in 4.

Second graph in the second line: is incorrect although it is a positive graph, it intercepts the y-axis in 3.

In the figure, b and c are parallel lines. Which of the following statements are true?
Helen [10]

Answer:

1. No, Joe is not correct

2. \angle 5=72^{\circ}

Step-by-step explanation:

Given: b and c are parallel lines

To find:

1. whether the given statement is correct or not

2. \angle 5

Solution:

1.

Sum of two angles that form a linear pair is equal to 180^{\circ}

\angle 3+72^{\circ}=180^{\circ} (linear pair)

\angle 3=180^{\circ}-72^{\circ}=108^{\circ}\neq 90^{\circ}

So, Joe is not correct

2.

If two lines are parallel then alternate interior angles are equal.

As b and c are parallel lines,

\angle 5=72^{\circ} (alternate interior angles)
