Answer:

∠A = 120°

∠B = 60°

Step-by-step explanation:

Since, ∠A and ∠B form a linear pair.

Therefore,

∠A + ∠B = 180°.....(1)

It is given that:

∠A = 2∠B..... (2)

From equations (1) & (2)

2∠B + ∠B = 180°

3∠B = 180°

∠B = 180°/3

∠B = 60°

So, ∠A = 2∠B = 2*60°

∠A = 120°

Consider this equation:
aleksandrvk [35]

Answer:

  • Plan: separate the variable term from the constant term; divide by the coefficient of the variable.
  • Steps: add 4 to both sides; collect terms; divide both sides by 3.

Step-by-step explanation:

The first step is to look a the equation to see where the variable is in relation to the equal sign, and whether there are any constants on that same side of the equal sign.

Here, the variable terms are on the left, and there is a constant there, as well. The plan for solving the equation is to eliminate the constant that is on the same side of the equation as the variable, then divide by the coefficient of the variable. To find that coefficient, we need to collect terms. In summary, the plan is to ...

  • add 4 to both sides of the equation
  • collect terms
  • divide by the coefficient of the variable (3)

Executing that plan, the steps are ...

  -2x -4 +5x +4 = 8 +4 . . . . add 4

  3x = 12 . . . . . . . . . . . . . . . collect terms

  x = 4 . . . . . . . . . divide by 3

A coordinate grid is placed over a college Station map. Tiger Stadium is located at (-3,2)
Olin [163]

Answer:

4.61\ units

Step-by-step explanation:

<em><u>The complete question is</u></em>

A coordinate grid is placed over a  College Station map.  Tiger Stadium is         located at (-3, 2) and Kyle Field is located at (4, 8).  If a shuttle bus stop is         at the midpoint between Tiger Field  and Kyle Field, which is the closest to         the distance in coordinate units from  Tiger Field to the shuttle bus stop?

<u><em>Options</em></u>

4.61 units

6.52 units  

9.22 units  

21.25 units

step 1

Find the midpoint between Tiger Field  and Kyle Field ( shuttle bus stop)

we know that

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

we have the points

(-3, 2) and (4, 8)

substitute in the formula

M=(\frac{-3+4}{2},\frac{2+8}{2})

M=(0.5,5)

step 2

Find the distance from  Tiger Field to the shuttle bus stop

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have the points

(-3,2) and (0.5,5)

substitute in the formula

d=\sqrt{(5-2)^{2}+(0.5+3)^{2}}

d=\sqrt{(3)^{2}+(3.5)^{2}}

d=\sqrt{21.25}\ units

d=4.61\ units

Pls help asapp picture attached
Olin [163]

Answer:

50

Step-by-step explanation:

Angle 1 is 110.

Angle 3 is 2x plus 10.

Angle 1 and 3 are vertically opposite angles.

And vertically opposite angles r equal.

Which means, angle 1=angle 3,and angle 2=angke 4.

Here we only Need angle 2 and 3.

Angke 2= angle 3.

Which is 2x plus 10=110.

Therefore 2x=110-10=100

Therefore x = 100÷2=50

There u have it ma'am.
