Answer: C: 3/5
Step-by-step explanation:
1/2 is equal to 5/10
so 5/10+1/10= 6/10
6/10 can simplify to 3/5
Answer:
3.5 m
Step-by-step explanation:
Use Pythagorean theorem to find the distance (d) the distance goes up the wall = adjacent to the angle 75° that is formed with the wall.
Length of ladder = the hypothenuse = 13.5 m
Thus, we would use:
Cos75 = adjacent/hypothenuse
Cos 75 = d/13.5
Multiply both sides by 13.5
13.5*cos(75) = d
13.5*0.2588 = d
3.4938 = d
d ≈ 3.5 m (nearest tenth)
Answer:

Step-by-step explanation:
Given the system of two equations:

Multiply the first equation and the second equation by 60 to get rid of fractions:

Now multiply the first equation by 4 and the second equation by 5:

Subtract them:

Substitute it into the first equation:

The solution is
I think it’s called tromino
