Answer:
x ≈ 14.4 cm
Step-by-step explanation:
the third angle of the triangle = 180° - 40° - 46° = 94°
Using the Sine rule in the triangle
= 
( cross- multiply )
x × sin94° = 20 × sin46° ( divide both sides by sin94° )
x = 
≈ 14.4 cm ( to the nearest tenth )
No because then somewhere in the problem you could multiply once more. like if u had 234 as ur answer, but had 2 as a remainder, u would change the 4 to a 5 (don't know if tht math is right, but the main idea of it is right)
Switch the y and x then solve for y, so I believe b.
Answer:
x + 10 = 4x
