Step-by-step explanation:
The ratio of the two shorter legs of the top triangle is
The bottom triangle has the following ratio:
Since their ratios are the same, this means that the two triangles are similar.
Answer:
Step-by-step explanation:
B=3x-2
C=12x+2
D=B=3x-2 (Vertically opposite angles)
A=?
Now; we know, A+B+C+D=360 deg.
=>A=360-(B+C+D)
=360-(3x-2+12x+2+3x-2)
=360-(18x-2) ----[1]
B+C=180 deg. (linear pair)
=> 3x-2+12x+2=180
=> 15x=180
=> x=180/15
=12 ---[2]
subsitute [2] in [1];
=> A= 360-(18x-2)
= 360-(18*12-2)
= 360-(116-2)
= 360-214
= 146 deg.
So, the correct answer is (D).
Hope the answer is useful.
If you are charging 5 per hour use h to determine how many hours and add 10 for the connection fee
5h+10
C, GHI because it is over 180 degrees and no triangle is over 180 degrees
