Slope-intercept form formula: y=mx+b
our slope is undefined.
X = original angle
3x = (90-x) - 14
3x = -x + 76
4x= 76
x = 19
The measure of the angle is 19 degrees
<u>Given</u>:
The radius of the circle is 4 cm.
The angle of the sector JKL is 135°
We need to determine the area of the sector JKL
<u>Area of the sector:</u>
The area of the sector can be determined using the formula,
Substituting 
, 
, we get;
Thus, the area of the sector is 18.84 cm²
If you multiply a certain number by 2.5, add 1.7 the expression is as follows:
2.5x + 1.7
<h3>Variables:</h3>
Variables are letters use to represent numbers in a mathematical expression.
Therefore,
let the certain number = x
The certain number is multiplied by 2.5.Therefore,
Then , we add 1.7 to the product of 2.5 and x. Therefore,
The final expression is as follows:
