Find the measure of the marked angles.

So you have 6x-20 and 4x+30. These angles are perpendicular to each other, meaning together they equal 180 degrees. To solve for this equation add both of the equations together equal to 180.
6x-20+4x+30=180
Now subtract: 30-20= 10 so 180-10= 170
Next add 6x to 4x= 10x
So 170=10x
X=17
Now we use substitution to simplify our answers into numerical form:
6(17)-20= 82 this is for 6x-20
4(17)+30= 98 this is for 4x+30
Hope that helps! :)

Hey, could someone please help me with this? Thanks.

Answer:

Part A: 1. (1, 0.5) 2. (2, 1) 3. (3, 1.5) 4. (4, 2) 5. (5, 2.5) 6. (6, 3)

Part B: Yes, this relation is in fact a function.

Part C: No, it would not be a function.

Step-by-step explanation:

Part A: Well, you start at 1 hr. right? yes. So then, at the very beginning at the problem, it says the candle burns at the rate of 0.5 in. per hour. So for 1 hour, the candle will burn .5 inches. At 2 hours, it will burn off 1 whole inch.

Part B:  1 hr. = .5 in. burn,  2 hrs. = 1 in. burns,  3 hrs. = 1.5 in. burns,  4 hrs. = 2 in. burns,  5 hrs.= 2.5 in. burns, 6 hrs. = 3  in. burns.

Part C:  1 hr.= .45 in. burn, 2 hrs. = .9 in burn,  3 hrs. = 1.35 in. burns, 4 hrs. = 1.8 in. burns, 5 hrs. = 2.25 in. burns, 6 hrs. = 2.7 in. burns.    It does not go at a constant rate. The number of inches are all over the place.

Hope this helps you out!! (:

The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if the perimeter of the triangle is 90 cm
svet-max [94.6K]
The sides of the triangle are 3x, 4x and 5x

3x + 4x + 5x = 90
12x = 90
x = 90/12
x = 7.5

first side = 3x = 3 * 7.5 = 22.5 cm
second side = 4x = 4 * 7.5 = 30 cm
third side = 5x = 5*7.5 = 37.5 cm

A triangle has a perimeter of 77 centimeters and one side is 25 centimeters. The other
Vitek1552 [10]

Answer:

  36 cm

Step-by-step explanation:

Let x represent the multiplier of the ratio units. Then the perimeter is the sum of the side lengths:

  77 = 25 + 4x +9x

  52 = 13x . . . . . . . . subtract 25

  x = 4 . . . . . . . . . divide by 13

  4x = 4(4) = 16 . . . . find the other side lengths

  9x = 9(4) = 36

The side lengths are 25 cm, 16 cm, 36 cm. The longest side is 36 cm.
