18 / 2 = 9 || 9 x 3 = 27. Therefore, 27 students are registered in Bob’s class.
Answer:
The height of the triangle is 3.2 cm.
Step-by-step explanation:
The area of the triangle = 
Base of the triangle = 10 cm
Height of the triangle = h cm
Area of the triangle = 

h = 3.2 cm
The height of the triangle is 3.2 cm.
- draw the points
- you will see thet AC has the same M as BD
- also AC = BD distance because it is a square
- calculate the M of AC

- calculate AC distance

- lets say d is (x,y)
- now just make to equations with BD distance and M
Step-by-step explanation:
a + b = 90
a + c = 180
a) If a = x, the. we can write
x + b = 90 and x + c = 180
or
b = 90 - x
c = 180 - x
b) c - b = (180 - x) - (90 - x)
= 180 - x - 90 + x
= 90
5/6, divide 3/4 to get 0.74 then divide 5/6 to get 0.84 for proof.
