The coordinates of the vertices of ANGLE RST are R(-3,5), and S(4,5), and T(4,-2). Find the side lengths to the nearest hundredt
e-lub [12.9K]


Side lengths: RS=7 and ST=7, and angle=90 degrees

Why?

Since second coordinates of R and S are the same so we can just count the length by adding first coordinate of R and first coordinate of S= |-3|+4=7

Since first coordinates of R is the same as first coordinate of T so we can just count  the length  by adding second coordinates of S and T=5+|-2|=7

Angle: RST is =90 degrees because triangle RST is right angled  triangle. Why? Because RS is parallel to X axis(the same second coordinates of R and S) and ST is parallel to Y axis(the same coordinates of S and T) .

Find the area of a parallelogram whose base is 12cm and altitude is 8cm. Also find the other base of its corresponding altitude
lukranit [14]

Answer:

Step-by-step explanation:

Area of parallelogram = base * height

                                    = 12 * 8

                                    = 96 cm²

Area of parallelogram = 96

base * height = 96

          base = 96/height

          base = 96/16

         base = 6 cm
