A woman wishing to know the height of a mountain measures the angle of elevation of the mountaintop as θ1 = 11.6°. After walking d = 0.81 km closer to the mountain on level ground, she finds the angle to be θ2 = 13.7°. a. Draw a picture of the problem, neglecting the height of the woman's eyes above the ground. b. Select variable names for the mountain height (suggestion:y) and the woman's original distance from the mountain(suggestion: x) and label the picture. (Do this on paper. Your instructor may ask you to turn in this work.)c. Using the labeled picture and the tangent function, write two trigonometric equations relating the two selected variables. (Dothis on paper. Your instructor may ask you to turn in thiswork.)d. Find the height y of the mountain by first solving one equation for x and substituting the result into the other equation.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
