Answer: Right ,vertical, supplementary

Step-by-step explanation:In the given figure the two rays are perpendicular.A line is said to be perpendicular to another line if the two lines intersect at a right angle.Thus <1 and <2 are Right angles.

The opposite angles formed by two intersecting lines are called vertical angles.<1 and <2 are on opposite sides of the two rays and hence form vertical angles.

The angles made at the intersection of the two rays are 90 degrees .So the sum of angles 1 and angle 2= 90+90=180 degrees.When two angles add to 180 degrees they are called supplementary angles .

Hence <1 and <2 are Right ,vertical, supplementary angles.

Let r vary directly with s and inversely with t. Which equation represents this equation? Assume that a is a constant.

$\bf \qquad \qquad \textit{combined variation}

\begin{array}{llll}
\textit{\underline{y} varies directly with \underline{x}}\\
\textit{and inversely with \underline{z}}

Solve for the equation for the interval [0, 2pi). sec x/2 = cos x/2

Alenkinab [10]

Sec(x/2) = 1/cos(x/2)

sec(x/2)=cos(x/2) ----> cos^2(x/2)=1 ---> cos(x/2) = -1 and cos(x/2) = 1

Cos(x/2)=1 --- > x/2 = 0, only. x = 0;

cos(x/2)=-1 ----> x/2 = pi -> x = 2pi. But the statement says [0,2pi), so 2pi can not be chosen.

Only x = 0.

In fact, your equation is equivalent to sec(x)=cos(x), for x in [ 0, pi), so yes, only x = 0 .

How can you write 1,360/200 as a repeating decimal?

Alisiya [41]

1360/200

13.6/2

6.8

It is a finite decimal, but if you want repeating, there are zeroes that follow, like so:

6.8000000000000 . . . (and on to infinity)
