Step-by-step explanation: <EDG = <EDF + <FDG
=86+66= 149
e know that the measure of arc in degrees is equals the measure of the central angle that intercepts the arc.
Now,the measure of arc EFG is given by Arc EFG=central angle EDG= 149
Answer:
315 cm²
Step-by-step explanation:
Given the scale factor of 2 similar figures is a : b , then
ratio of areas = a² : b²
Here the scale factor = 7 : 21 = 1 : 3 , thus
ratio of areas = 1² : 3² = 1 : 9
That is the area of the enlargement is 9 times the original, so
area of enlargement = 35 × 9 = 315 cm²
