Answer:
18 cm²
Step-by-step explanation:
Base * half height says 6*6/2 = 18.
The trick is to put the 90° angle at the base (rotate the triangle).
I believe the answer is y=3x+2
Answer:
8:5
Step-by-step explanation:
Number of red beads = 15
Number of blue beads = 24
ratio of beads in blue : red
= 24 : 15
= 8 : 5 ...............(reducing by 3)
Answer:
72 inches
Step-by-step explanation:
The total in ratio would be 3 + 4 + 5 = 12
The largest side is the ratio of "5". Now we can setup a proportionality and solve for other sides:
Let smallest side (3) be x and 2nd largest be (4) y. SO,
18 is the smallest side.
Also
2nd largest side is 24
We know largest side is 30
Thus perimeter (sum of 3 sides) = 18 + 24 + 30 = 72 inches
