Answer:
A complementary angle is 63 degrees and supplementary angle is 153 degrees.
Step-by-step explanation:
Complementary angle:
A complementary angle adds up to 90 degrees, so you have to subtract 27 from 90. 90-27=63
Supplementary angle:
A supplementary angle adds up to 180 degrees, so you have to subtract 27 from 180. 180-27=153

Answer:
On a coordinate plane, a parabola opens down
has a vertex at (negative 0.5, 6.75)
The vertex is the maximum value. The axis of symmetry is x = negative one-half.
The domain is all real numbers
Step-by-step explanation:
Answer:
Let the three angles be 2x,9x & 4x
By the problem,2x+9x+4x=180
15x=180
x=180/15
x=12
there fore the angles are
2x= 2*12=24°
9x=108°
4x=48°
