- AC is congruent to itself
- AC bisects angle BAD, so that angles BAC and DAC are congruent
- Both angles B and D are right angles, so they are congruent
This means triangles BAC and DAC are a pair of angle-angle-side triangles, so they are congruent to one another. Corresponding parts of congruent triangles are congruent, so the line segments BC and DC are congruent and have the same length.
Then
If you use the property of substitution, you can get (-2, 6.5) as your answer. Substitute the value of X (-2) in the initial equation and solve for Y.
Y= -3/4 (-2) +5 ( I am sure you inadvertently put the Y here also)
Y= 6/4 + 5
Y = 6.5
Answer:
slope = - , point on line = (4, - 3 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
y + 3 = - (x - 4) ← is in point- slope form
with slope m = - and point on line (a, b ) = (4, - 3 )
A = 6. The area is base times height divided by 2 so (3*12)/2 = 6
