What is manglevsr? 2 lines intersect. a horizontal line has points r, s, u and intersects a line with points v, s, t at point s. angle v s u is 100 degrees.

80°

Step-by-step explanation:

Plot two lines: line passing through the points R, S and U and line passing through three points V, S and T (see attached diagram).

These line intersect at point S and form four angles: RSV, VSU, UST and TSR.

Angles VSU and RST are vertical angles, angles RSV and UST are vertical angles. Vertical angles are congruent, so

m∠VSU = m∠RST = 100°

m∠RSV = m∠UST

Angles RSV and VSU are supplementary angles (add up to 180°). Som

m∠RSV = 180° - m∠VSU =180° - 100° = 80°

Angle RSV is angle VSR (we can read from the right to the left or from the left to the right angle's name)

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
