Answer:
x = 16
Step-by-step explanation:
The diagram can be misleading because angle A does not correspond to angle F. Rather angle F corresponds to angle C.
In congruent triangles, corresponding angles have the same measure. The sum of angles is always 180°, so we have ...
... m∠A +m∠B +m∠C = 180°
... (3x+6)° +50° +(9x -68)° = 180°
... 12x -12 = 180 . . . . . divide by °, collect terms
... x -1 = 15 . . . . . . . . . .divide by the coefficient of x
... x = 16 . . . . . . . . . . . add 1
_____
<em>Check</em>
m∠A = (3x+6)° = 54°
m∠C = (9x -68)° = 76°
The total of angles is 54° +50° +76° = 180°. . . . . as it should be
Answer:
A= -6
B= 6
C= 9
Step-by-step explanation:
Answer:
<h3>The slope of line B would be
-5</h3>
Step-by-step explanation:
Multiply the current slope by its negative inverse (flip the fraction and multiply it by -1).
Answer:
He was supposed to cross multiply the equation in the original equation. Step 2 was a wrong expression
Explanations:
The given equation is:
Cross multiply the equation, the equation becomes:
x = 8 - 12
x = -4
His mistake was in step 2, he did not properly expand the equation
The proper step was to cross multiply in step 2
The distance between (0,3) and (3,0) = sqrt 18
The other 3 distances on the rhombus must also be = sqrt18.
Distance between (3,6) and (6,3) = sqrt 18 , also distance between (3,6 and (0,3) = sqrt18 and distance between (3,0) and (6,3) = sqrt 18
Answer is (3, 6) and (6 , 3)
