From the question, we understand that G is a point between D and M:
This implies that:

Substitute values for DM, DG and GM

Solve for r


B= 60
To find b you must do the pythagorean theorem because it is a right triangle
65^2 - 25^2=b^2
3600=b^2
60=b
x= 18
To find x you must know that a triangle is made up of 180 degrees.
x= 180-(72+90)
x=180-162
x=18
hope this helped :)
Answer:
i think it is 18 but i may be wrong
Step-by-step explanation:
3 every 10 minutes
10 x 6 is an hour so you have to multiply 3 by 6 as well
3 x 6 is 18
