The answer would be 63 bc 46+71= 117 then a triangle usaually equals 180 so 180 -117=63!!
The model is 1:50 so take 11/5 and multiply it by 50 and you get 110, so the window is 110 inches long
12.) First find the rate of miles/hour that the Morales family drove: 312 miles/6 hours = 52 miles/hour. To find how far they travel in 8 hours, multiply that rate by 8. 52 x 8 = 416. If they drive for 8 hours, they will travel 416 miles.
Another quadrilateral that you might see is called a rhombus. All four sides of a rhombus are congruent. Its properties include that each pair of opposite sides is parallel, also making it a parallelogram. In summary, all squares are rectangles, but not all rectangles are squares.
