Answer:
One
Step-by-step explanation:
x+4y = 6
if why is 2x-3 plug it in
x+4(2x-3) = 6
simplify it and you get
x=2
Its t-h
because the sinB = AC/AB (=h) and the cosB= CB/AB but the sinA = CB/AB and the cosA =AC/AB
=> SinB = CosA= t; CosB = sinA=h
=>SinA-CosA = t-h
Hi there!

Collect terms.

Subtract 2 from both sides.

Divide both sides by 11.
