Two angles are supplementary. The larger angle is
UkoKoshka [18]

Answer:

x = 165, y = 15

Step-by-step explanation:

1. Well, what does supplementary mean? - The angles add up to 180°.

2. Let's form an equation: x + y = 180°

3. Let's say x is the larger angle and y is the smaller angle.

4. Let's form another equation: x = 150 + y

5. Put the two equations next to each other:

x + y = 180

x = 150 + y

6. We know what x is equaled to, so let's plug it into the first equation!

150 + y + y = 180

150 + 2y = 180

-150           -150

2y = 30

y = 15

7. Now, we know what y is, let's find x!

x + 15 = 180

   -15     -15

x = 165

Differnece between 2x+4 and 3x+4 and 4x+4
prohojiy [21]

Answer:

the difference is the slope

Step-by-step explanation:

y = mx+b

m is the slope

b is the y-intercept

2x+4

3x+4

4x+4

the m constant changes meaning the slope is the difference

Suppose that α and β are the angles of a triangle. It is known that: 58°≤α≤59° and 102°≤β≤103°. Find the possible values of the
IceJOKER [234]

The possible values of the third angle are from 18° to 20°

Step-by-step explanation:

The sum of the measures of the angles in any triangle is 180°

The given is:

1. α and β are two angles of a triangle

2. 58° ≤ α ≤ 59°

3. 102° ≤ β ≤ 103°

Assume that the third angle is Ф

∵ α + β + Ф = 180°

- Subtract α + β from both sides

∴ Ф = 180 - (α + β) ⇒ (1)

∵ 58° ≤ α ≤ 59°

∵ 102° ≤ β ≤ 103°

- Add the two inequalities

∴ 160° ≤ α + β ≤ 162°

- By substituting α + B = 160 in equation 1

∴ Ф = 180 - 160

∴ Ф = 20°

- By substituting α + B = 162 in equation 1

∴ Ф = 180 - 162

∴ Ф = 18°

- Put Ф in the form of inequality

∴ 18° ≤ Ф ≤ 20°

The possible values of the third angle are from 18° to 20°
