One of the angles formed by two intersecting lines is 4 times greater than the other. Find these angles.

Mathematics
1 answer:
Morgarella [4.7K]4 years ago
5 0

Answer:

The angles are 36° and 144°

Step-by-step explanation:

Let

x-----> one of the angles formed by two intersecting lines

y----> the other angle formed by two intersecting lines

we know that

x+y=180° -----> Equation A (by supplementary angles)

x=4y -----> equation B

substitute equation B in equation A

4y+y=180°

5y=180°

y=36°

Find the value of x

x=4(36°)=144°

therefore

The angles are 36° and 144°

What are the characteristics of the function f(x) = 2(x-4)5?
Ivanshal [37]

Answer:

Step-by-step explanation:

Answer: Options F, E, C.

Given : function f(x)=2(x-4)^5.

To find : What are the characteristics of the function .

Solution : We have given that f(x)=2(x - 4)^5.

By the End Point behavior : if the degree is even and leading coefficient is odd of polynomial of function then left end of graph goes down and right goes up.

Since , Option F is correct.

It has degree 5 therefore, function has 5 zeros and atmost 4 maximua or minimum.

Option E is also correct.

By transformation rule it is vertical stretch and shift to right (B )

Therefore, Option F , E , C are characteristics of the function .
