Three angles are in the ratio 2:3:5
The smallest angle is 50
Work out the sizes of the other two angles

Answers

Answer:

The other two angles are 75° and 125°.

Step-by-step explanation:

Let three angles are 2x, 3x and 5x.

The smallest angle is 50.

It means,

2x = 50

x = 25

So,

3x = 3(25) = 75°

5x = 5(25) = 125°

So, the other two angles are 75° and 125°.

w-7=-4 i do not no this one please help me

Answers

Answer: i believe what you're looking for is W so, W=3

Step-by-step explanation: you add +7 to each side of the equation, which gives you W=3

Answer:

w= 3

Step-by-step explanation:

Add 7 to both sides of the equation w-7 = -4

w-7+7=-4+7

Simplify : w-7+7=-4+7 which simplifies to w= -4 +7

So, w = -4 +7 is w= 3

0.8 = 0.5x

Solve for x

Please show steps thanks so much

Answers

If I’m not mistaken, to solve for x you have to get it by itself so you need to divide 0.5 from both sides:

0.8/ 0.5 = 0.5x/ 0.5

Cross out the 0.5’s on the right because they cancel out and you will end up with:

0.8/ 0.5 = x

All you have to do then is divide 0.8 by 0.5 and you get:

1.6 = x

. Center at (-4,-1), radius = 2

Answers

Consider we need to find the equation of the circle.

Given:

The Center at (-4,-1), radius = 2.

To find:

The equation of the circle.

Solution:

The standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where, (h,k) is the center of the circle and r is the radius of the circle.

Putting h=-4, k=-1 and r=2, we get

[tex](x-(-4))^2+(y-(-1))^2=(2)^2[/tex]

[tex](x+4)^2+(y+1)^2=4[/tex]

Therefore, the equation of the circle is [tex](x+4)^2+(y+1)^2=4[/tex].
