Answer:
see explanation
Step-by-step explanation:
Given AB ≅ BC, then
AB = BC = x + 6 , and
AC = AB + BC ← substitute values
3x - 31 = x + 6 + x + 6, that is
3x - 31 = 2x + 12 ( subtract 2x from both sides )
x - 31 = 12 ( add 31 to both sides )
x = 43
Hence
AB = BC = x + 6 = 43 + 6 = 49
AC = 3x - 31 =(3 × 43) - 31 = 129 - 31 = 98
Answer:
Answer is 62 degrees.
Step-by-step explanation:
The sum of all angles of a triangle is 180°
x + 70 + 48 = 180
x + 118 = 180
x = 180 - 118
x = 62
A²=25 then a = + 5 & a =-5, so this ellipse intercepts the x axis at the points +5 & -5
Answer:
Step-by-step explanation:
Given is the piecewise function.
The first part is increasing function y = x + 6, when x ≤ -3
The second part is decreasing function y = -x when x > -3
The above is reflection in the first graph (top one)
