Find the measurement of both complementary angles, if:

We are given one angle that is 3 times less than others. Let us assume one angle measure is x degrees and another is 4x. Because x is 3x less than 4x.            ( We can check 4x-x= 3x) Sum of complementary angles is 90 degrees. So, we can set up an equation, First angle measure + first angle = 90 degrees. x+4x = 90. Adding x and 4x, we get 5x. So, 5x = 90. Dividing both sides by 5, we get 5x/5 = 90. x= 18. So, one angle is 18 degrees. Another angle = 4x = 4 times 18 = 72 degrees. So, the required angles are of 18 degrees and 72 degrees.

I don't know if you have any other information, but it looks like the corner of the house is at the center of the circle, making 20 the radius. The dog can only ever be 20 feet away from the house. With the information given, that is all you can find.

13. Whats the domain and range? <br> 14. What’s the domain and range?
jonny [76]

Answer:

See below

Step-by-step explanation:

13) Domain: x -> {-3,-2,-1,0,1,2}, Range: f(x) -> {5}

14) Notice how x can't be -4 as that will make the denominator 0. Therefore, your domain is (-∞,-4)U(-4,∞) and your range is [0,∞) since 0 is the lowest possible real y-value that satisfies the equation (recall that if y<0, you are unable to find the real square root of a real number)
