Answer:
1. 2x + 5
2. 35 students walked
3. 1:18
Step-by-step explanation:
Using Pythagorean theory the square of the hypotenuse minus the square of the base equals the square of the other side (altitude).
So 8*8=64, 4*4=16, 64–16=48 so the altitude of the triangle is the √48.
Answer:
20
Step-by-step explanation:
Vertical angles are always equal to each other. So the answer is
3x + 4 = 73 - 9 Are you sure this is what the question is?
3x + 4 = 64 Subtract 4 from both sides
<u> -4 -4</u>
3x = 60 Divide by 3
3x/3 = 60/3
x = 20
