De uma viga de madeira de seção quadrada de lado 10 cm extrai-se uma cunha de altura 15 cm , conforme a figura. Determine o volume da cunha.

Which of the following describes supplementary angles? A. Angles that areadjacent. B. Two or more angles whose sum equals 360 degrees. C. Two angles whose sumequals 180 degrees. D. Angles whose measurements equal 90 degrees.

Estimate the measure of this angle within \( 10^{\circ} \).

11 Find the unknown angles in the figure and place the correct value into the box. Assume that the lines are parallel. DRAG \& DROP THE ANSWER Note: Use CTRL+D to drag the option via keyboard

Analyze the equation. That is, find the center, vertices, and foci of the ellipse and graph it. \[ \frac{x^{2}}{49}+\frac{y^{2}}{4}=1 \]

Find the standard form of the equation of the ellipse satisfying the given conditions. Foci: \( (-2,0),(2,0) ; y \)-intercepts: -9 and 9 Type the standard form of the equation. (Type an equation. Simplify your answer.)
