P=q is the answer
since both triangles have equals sums of the known angles (60+30=90, 45+45=90)
p must be equal to q
Answer:
the marked answer is correct
Step-by-step explanation:
The desired end result is an identity matrix in the first three columns. The diagonal values are 1, as needed, so what remains is to eliminate the off-diagonal values. In row 2 that can be done by adding row 3 to it.
The next step should be to add rows 2 and 3 and replace row 2 with that sum.
Answer:
-3x + 3y - 6
Step-by-step explanation:
2x + 3y - 4 - (5x + 2)
open brackets by using - sign to multiply
2x + 3y - 4 - 5x - 2
collect like terms
2x - 5x + 3y - 4 - 2
-3x + 3y - 6
I got this. Bottom of the triangle. that flat line is 180 degrees. you have an angle of 120, leaving an angle of 60. if you look at the top, that angle matches the other. so you have 65 degrees on one side, and 60 on the other. so 180-65-60=55. so X=55
