6 acts as the base. 15 acts as the height, because it extends from the base to meet vertex opposite the base at a 90° angle.
General formula for triangle area
a = 1/2 × b × h
plug in the numbers
a = 1/2 × 6 × 15
a = 90/2
a = 45
The area of the triangle is 45 units²
Answer:
8b is 220
Step-by-step explanation:
it might be 220 because we already know that from o to b is 140 degrees. We know that a full circle is 360, so take 140 away from 360, and you get 220.
360-140=220 degrees
Im not sure about the other questions but i hope this helps :)
Working shown, hopefully it helps
The greatest common factor between 6 and 15 is 3.
You can reduce 6/15 down to 2/5.
