Answer:

Step-by-step explanation:

Legs are the sides of an isosceles triangle that aren't the base, so in this case ZX would be the base. This rule is only for isosceles triangles. It doesn't apply to any other type of triangle.

Hope I helped, sorry if I'm wrong!

Answer:

Step-by-step explanation:

The legs of a triangle are the 2 sides in the triangle that are not the hypotenuse, the side opposite the right angle.

The hypotenuse is XY, thus

The legs are YZ and ZX → C

the equation of the line a is given as y = -3/4 x -2. Suppose the line a is parallel to line b and lime t is perpendicular to li

Burka [1]

Answer: The equation for line b is $y = -\frac{3}{4}x + 5$

The equation for line t is $y= \frac{4}{3} x+5$

The attachment shows the original line in green, the parallel line b in red, and the perpendicular line t in blue.

Step-by-step explanation: Use slope intercept form, y = mx + b

The given coordinate, (0,5) is on the y-axis, so 5 will be the y-intercept of the equation. Keep the slope of the original equation and substitute the new value for "b"

To write the equation for line t

Both lines share the y-intercept, (0,5) so the "b" term will be the same. The slope of a perpendicular line is the reciprocal of the original slope with the opposite sign.

So invert 3/4 to become 4/3 and change the negative sign to positive.

The resulting equation is y = 4x/3 + 5

If y is directly proportional to x squared and y = 3 when x = 2, what is y when x = 8?

Anestetic [448]

Answer:

y = 63

Step-by-step explanation:

y is directly proportional to x²

As given,

when y = 3 => x = 2

So, 3 = 4 - 1

Which means the relation can be written as :-

y = x² - 1

Substituting x = 8

y = (8)² - 1

y = 64 - 1

y = 63

Answer: tan θ

Step-by-step explanation:

cotθ * sin²θ * sec²θ

= $\frac{cos}{sin} * \frac{sin*sin}{1} * \frac{1}{cos*cos} = \frac{sin}{cos}$ = tan
