images hold the questions (only 3)

answer:

for the drag in box one equations are like this

3=4r ÷ 4

the other one is just words

x=10

Step-by-step explanation:

Because the image shows a right angle, we know it's 90 degrees. the two angle measures added together to create the 90 degrees are represented by 4x and 5x, so;

4x+5x=90 (combine like terms)

9x=90 (divide each side by 9 to isolate the variable)

x=10
