find the supplementary angle of 9+ A + b degree
Answers
Answer:
162°
Step-by-step explanation:
Let the angle bex, then its complementary angle will be(900−x)
and supplementary angle will be(1800−x)
now, it is given in the question that the supplementary angle of an angle is94times its complementary angle, that is
(1800−x)=(94)(900−x)
4×(1800−x)=9×(900−x)
4×(1800−x)=8100−9x
7200−4x=8100−9x
−4x+9x=8100−7200
5x=900
x=9005
∴x=180
Therefore, the supplementary angle=1800−180=1620
Hence, the required solution is 162° .
Answer:
171° - a - b
Step-by-step explanation:
Hey
See my explanation
In Math, two angles are said to be supplementary, when the angles add up to 180 degrees.
We know that the sum of supplementary angles is 9° + a + b
Let the unknown angles be x
Thus,
(9° + a + b) + x = 180°
X = 180° – (9° + a + b)
X = 171° - a - b
Hence, the required solution is 171° - a - b .
Hence, the unknown angle is 171° - a - b (because we dont know what a and b is we just have to subtract it from the angle A as you saw in my workout!
Hope it helped! :)
