The individual angle measures of triangle JKL are;
Here, we want to find the measure of each angle in triangle JKL
Let us start this by assigning a variable to represent angle j
Let us have the variable as x
Angle k is nine more than angle j
Thus;
Furthermore, L is 21 less than two times the measure of angle J
Mathematically, the sum of the angles of a triangle is 180
Thus, we have it that;
Thus, we have the measure of angke J as 48
For K and L, we simply substitute the value of x
We have;
