What is x equal to????

x = 20

Step-by-step explanation:

The 3 arcs UV, VW, WX form a semicircle, so sum to 180° , that is

4x + 2 + x + 78 = 180

5x + 80 = 180 ( subtract 80 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20

The length of the beetle in the drawing is 9 cm.

Step-by-step explanation:

Hi, since is a scaling up scale, we have to multiply the original length of the beetle (1.8 cm) by 5 to obtain the length of the beetle in the drawing.

Mathematically speaking

5 x 1.8 = 9 cm

The length of the beetle in the drawing is 9 cm.

This type of scale is used to increase in size.
