Answer:
A
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosA =
=
=
, thus
A =
(
) ≈ 48° → A
Answer:
option 1 i think
Step-by-step explanation:
The slope/intercept form of the equation of a straight line is
Y = (slope) X + (y-intercept) .
You know the slope and the y-intercept.
All you have to do is take that equation and fillum in.
Given a square ABCD and an equilateral triangle
DPC and given a chart with which
Jim is using to prove that triangle APD is
congruent to triangle BPC.
From the chart, it can be seen that Jim proved that two corresponding sides of both triangles are congruent and that the angle between those two sides for both triangles are also congruent.
Therefore, the justification to complete Jim's proof is "SAS postulate".
