Answer:

60 degrees.

Step-by-step explanation:

A reflection does not alter the size of the angles of the triangle so B = 60 degrees.

If the radius of the circle is 4 cm, find its circumference. [Use 3.14 for π.]

Rudik [331]

$r=4 \ cm \\ \pi=3,14 \\ \boxed{C-?} \\ \bold{Solving:} \\ \boxed{C=d \cdot \pi=2r \cdot \pi} \\ C=2 \cdot 4 \ cm \cdot 3,14=8 \cm \cdot \pi \\ \Rightarrow \boxed{C=25,12 \ cm}$

Given side 28 is equal to side 4
28÷4=7

therefore times all numbers on smaller shape by 4 to get sides of larger shape, add the numbers on larger shape together to equal 238

Perimeter of larger shape is 238
