If triangle abc is similar to def
That means all angles are the same and sides will be multiplied by some factor x. So AB(x)= DE
8x=24
Therefore x =3
Now BC=EF/x
BC=42/3
BC= 14
Answer:
B. Complementary Angles
Step-by-step explanation:
They both make up 90 degree angle.
Answer:
B :
Step-by-step explanation:
If you divide a rhombus using its diagonals, you get 4 right triangles, whose legs are both 1/2 the length of the diagonals.
This means that the legs of one of those 4 triangles have lengths of 2x/2, and 8x/2, so the legs of one of those triangles x and 4x. This makes the length of one side equal to
. Because all 4 sides are the same length, you multiply this value by 4, and get
, which is B.
the answer is 120 bc 140 is adjacent to it and 140-20 = 120
