two angles are supplementary. if one angle has a measure twice the other angle, what are the measures of the angles

1 answer:

5 0

Supplementary = equal to 180 degrees.

We can set up an equation.

2x + x = 180

Combine like-terms:
3x = 180

Divide both sides by 3 to isolate the x.

x = 60.

So one angle is 60 degrees and since the other one is twice of x, it is 120 degrees. If you add 120 and 60 degrees, you should get 180 degrees.

Nevertheless, the measures of the angles are 60 and 120 degrees.

Can someone show me how to do this? I’m not sure how to do this

Allushta [10]

Answer: Slope means the gradient. So find the equation of the line first then graph the points on the graph.

Step-by-step explanation:

y=mx+c *We want m*

m=(y2-y1)/(x2-x1)

m=(0-1)/(6-3)

m=-1/3

y=-1/3x+2 *(0,2) co-ordinate means it's the y-intercept=c*

I think the slope is -1/3 and then just plt the points on the graph manually.

Siddique is making a wedding cake. He needs 2.5 kg of flour. Each bag of flour weighs 500g. How many bags will he need to buy?

Answer:

You need to buy 5 bags of flour

Step-by-step explanation:

Each bag is 500g and needs 2.5kg.

If we replace 2.5kg it goes to 2500g.

2500g / 500g = 5 bags
