In the following square, fill in all angles and side lengths.

Step-by-step explanation:

the shape is a square (meaning all sides are equal)

CR = AR = CA=AT=AR=AT=RT=RS=ST=CS=4

the triangle in a square is an equilateral triangle meaning all sides are equal

the sum of angles in a triangle is 180°

all the angles in each triangle is 180/3 = 60°

the sum of angles in a square is 360

the angles at each angles ∠A =∠T=∠S= ∠C = 360/4 = 90°

$62.85

Step-by-step explanation:

Given data

ratio=  10: 7: 5

Total ratio= 10+7+5= 22

Lisa= $20

Her proportion of the ratio = 7

Applying the part to all method

Let the total amount shared be x

7/22= 20/x

cross multiply

7x= 22*20

7x= 440

divide both sides by 7

x= 440/7

x= 62.85
