Answer:
A
54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and the adjacent leg of 36° are the same leg in the triangle.
Step-by-step explanation:
The answer explains itself.
The sum of angles in a triangle is 180°. When one of the angles is 90°, the sum of the other two angles is also 90°. That means those two acute angles are <em>complementary</em> (not supplementary).
The mnemonic SOH CAH TOA reminds you that ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Answer:
Solution given:
y+135°=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]
y=180°-135°
y=25°
again
2x-1+3x+1=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]
5x=180
x=180/5.x=36

Answer:
yes
