The triangle ABC is equilateral.
⇒ AB = BC = AC
6x - 3 = 5x ⇒ 6x - 5x = 3 ⇒ x = 3 cm
6x - 3 = 3x + 6 ⇒ 6x - 3x = 6 + 3 ⇒ 3x = 9 ⇒ x = 9/3 = 3 cm
5x = 3x + 6 ⇒ 5x - 3x = 6 ⇒ 2x = 6 ⇒ x = 6/2 = 3 cm
<h2>⇒⇒⇒ x = 3</h2>
AB 6x - 3 = 6 - 3 + 3 = 18 - 3 = 15
AC = 3x + 6 = 3 × 3 + 6 = 9 + 6 = 15 cm
BC = 5x = 5 × 5 = 15 cm
<h2>⇒⇒⇒ AB = AC = BC = 15 cm</h2><h2 /><h2 />
Answer:
everything is correct
Step-by-step explanation:
you did a good job
Answer:
y = 9
Step-by-step explanation:
the equation of a horizontal line parallel to the x-axis is
y = c
where c is the value of the y-coordinate the line passes through
the line passes through (15, 9) and (- 2, 9)
both points have y-coordinate of 9, hence
y = 9 ← is the equation of the line
124+(2x+4) = 180
2x = 52
x = 26
Note: supplementary angles means that sum of the two angles is 180 degrees
