Answer:
33 sq. units
Step-by-step explanation:
The area of a sector can be calculated using the formula;
From the given information, the area of the circle is 36 and the angle of sector is
This means
We substitute the values into the formula to get:
We cancel out common factors to get:
The area of sector is 33 square units
ANSWER
x = 4
EXPLANATION
1) 1+4x = 13+x
2) 1+3x = 13
3) 13 - 1 = 12
4) 3x = 12 (Solve for x by dividing 3 on both sides)
5) x = 4
You know the total length ST and SU, so to find x you would write an equation. This would be: x+4+2x=16 Combine like terms: 3x+4=16 Subtract four from both sides: 3x=12 Divide both sides by three: x=4
