Answer:
x = 22°
the angles are: 63° and 117°
Step-by-step explanation:
a linear pair of angles total together to be 180°
so:
3x - 3 + 5x + 7 = 180
combune like terms:
8x = 176
divide both sides of the equation by 8:
x = 22°
the angles are: 63° and 117°

Answer:
Step-by-step explanation:
take angle A as reference angle
using cos rule
cos A=adjacent/hypotenuse
cos A=12/13
cos A=0.92
A=cos 23
A=23 degree
for ratio,
cos A=12/13
