Answer:
4 is your answer
Step-by-step explanation:
in triangle
60+70+13x-2=180 sum of interior angle of the triangle is 180
128+13x=180
13x=180-128
x=52/13=4
Answer:
6, 8, 10, 12, 18, 20
Mean: 6 + 8 + 10 + 12 + 18 + 20 = 74/6 = <em>12.3</em>
Median: <em>11</em>
Mode: <em>there are no mode in the following listed numbers or data set.</em>

Answer:
sin70° = x/6
Step-by-step explanation:
When we draw out our picture and triangle, we should see that our angle is on the ground 70°, the height <em>x</em> is across from the angle and is the vertical leg up, and that our hypotenuse is equal to 6:
sin70° = x/6
Q -------------R------------S
suppose this is your line,
R is the mid point
and it's given that
QR = 2x
and
RS = x+3
as R is the mid point of QS
so,
QR = RS
then,
2x = x + 3
2x - x =3
x = 3
as,
it's given that RS = x + 3
then,
RS = 3 + 3
= 6 units.
Let Angle A = X
Since Angle B is the same, angle B is also X
Then angle C = X +45
Add the 3 angles together: X +X +X +45 = 3x+45
That equals 180 degrees:
3x+45 = 180
Subtract 45 from both sides:
3x = 135
Divide both sides by 3:
X = 135/3
X = 45
Angle A = 45
Angle B = 45
Angle C = 45+45 = 90
