Answer: 9
Step-by-step explanation:
A=(a+b)/2 *h
135= 30/2* h
135= 15 * h
135/15= h
9=h
Answer:
4.082 radians
Step-by-step explanation:
Here we want to convert 234° into radians.
To do it, we use the fact that pi radians is equal to 180°
Then we can write two equations:
x radians = 234°
3.14 radians = 180°
Where we want to find the value of x, which is the equivalent in radians to 234°.
Now we can take the quotient of these two equations to get:
( x radians)/(3.14 radians) = (234°/180°)
Solving this for x, we get:
x radians = (234°/180°)*(3.14 radians) = 4.082 radians.
Answer:
Step-by-step
To convert radians to degrees, multiply by 180π , since a full circle is 360° or 2π radians.
