Answer:

x = 24

Step-by-step explanation:

Sum of the interior angles in the triangle is 180 degrees

So,

72 + 64 + 4x +20 = 180\\

Now solve for x

72 + 64 + 4x +20 = 180\\\\156 + x=180\\x=180-156\\x=24

<em>hope this helps you</em>

<em>please let me know if you have any other questions :-)</em>

  • We know, sum of all angles of a triangle is 180°.
  • Therefore, by the problem

72 + 64 + (4x+20) = 180

or, 156 + 4x = 180

or, 4x = 180 - 156

or, 4x = 24

or, x = 24 ÷ 4 = 6

<h3><em>Your </em><em>answer </em><em>is </em><em>6</em><em>.</em></h3>

Answer:

(-1, 6)

Step-by-step explanation:

The midpoint of a line segment is effectively the point that lies halfway between two pairs of coordinates on a line. The coordinates we're concerned with here are (-4, 10) and (2, 2). So first think about what is halfway between -4 and 2 (or you can add -4 and 2 then divide by 2) and do the same with 10 and 2. This will give you (-1, 6).

What is the measure of ∠x?
Dima020 [189]
The angle is a complementary angle so both angles add up to 90 degrees

Therefore set your equation equal to 90 to find angle of x

53+x=90

Subtract 53 from both sides

X= 37 degrees

If a person uses $700 in credit with an interest of 14%,what is that person going to owe after three billing cycles with simple
Brums [2.3K]
Simple interest:  i = p*r*t, where r is the annual interest rate and t is the number of years.
                                14%
This boils down to ----------- interest per month:  a monthly rate of 0.0117.
                                12 mo

Thus, after 3 months, the amount owed, including the original $700, would be $700 + 3($700)(0.0117) = $724.57.
