:in a right triangle abc, tan(a) = 3/4. find sin(a) and cos(a). in a right triangle abc with angle a equal to 90 degrees, find angle b and c so that sin(b) = cos(b).

Tan is equal to sin over cosine so if this is all the info you are given sin.is 3 and cosine is 4. However it is possible term cancel out like sin could be 3/5 and cosine 4/5 which would still give tan 3/4. Actually that is probably what it is to make a 3 4 5 triangle.
To make sine and cos equal the opposite and adjacent sides must be equal. By corresponding angles it is isosceles so b and c must be 45

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
