Ill assume it is :-
tan^2 A - 2 tan A + 1 = 0
(tan A - 1)^2 = 0
tan A = 1
m < A = 45, 225 degrees ( where 0 < m A < 360 )
Answer:
See below
Step-by-step explanation:
we have f(x) = -(x-7) + 3
and we want to find f(4)
essentially, f(4) means that the input is 4 and to find the output we plug in the value of the input where ever x is and evaluate.
So for f(x) = -(x-7) + 3
To find f(4) we replace all x's with 4
f(4) = -(4-7) + 3
we now evaluate
==> subtract 7 from 4
f(4) = -(-3) + 3
==> apply two negative rule ( basically if there are two negative signs they cancel out and the number turn positive )
f(4) = 3 + 3
==> add 3 and 3
f(4) = 6
Here's one example.
1) Catering Costs
"celebrations" offers catering services. They charge 30 dollars initially, and 1.5 dollars per person.
a) C representing cost and P representing people. The equation of this relation is C = 1.5p + 30
b) C P
32 1
33.5 2
35 3
36.5 4
(The table can be used to make points)
(p,C)
c) You can rewrite this in standard form.
C = 1.5t + 30
0 = 1.5t - C + 30
-30 = 1.5t - C
30 = -1.5t + C
Another example:
2) Transportation.
A car is driving from City A to City B at a constant speed of 80km/h The distance away from both cities is 240km.
a) In which D represents distance in km and T represents time in hours, an equation that can represent the distance away from City B is D = -80t + 240
b) D t
160 1
80 2
0 3
(These can be used to make points)
c) You can rewrite in standard form.
D = -80t + 240
0 = -80t - D + 240
-240 = -80t - D
240 = 80t + D

-1/4+6/n
-n+24/4n
The triangles would be congruent because of the two Triangle Congruence Theorms.
ASA: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
SAS: If any two angles and the included side are the same in both triangles, then the triangles are congruent.
Because your triangle has more than two angles that are congruent, and more than one side that are congruent, it more than fits the theorms.
Hope this helps.
