• The base of the triangle is $\overline{JK}$,
• The measure of $\angle J$ is given as $(5x - 20)^\circ$,
• The measure of $\angle L$ is given as $(3x + 25)^\circ$.

You are asked to find the degree measure of each angle in the triangle.

Step-by-Step Solution:

In an isosceles triangle, the two base angles are equal. Therefore, $\angle J$ and $\angle L$ must be congruent. So, we can set the two expressions for the angles equal to each other:

$5x - 20 = 3x + 25$

Now, solve for $x$:

1. Subtract $3x$ from both sides: $2x - 20 = 25$
2. Add 20 to both sides: $2x = 45$
3. Divide both sides by 2: $x = 22.5$

Now, substitute $x = 22.5$ back into the expressions for $\angle J$ and $\angle L$:

• $\angle J = 5(22.5) - 20 = 112.5^\circ$,
• $\angle L = 3(22.5) + 25 = 92.5^\circ$.

Finally, the angle at $\angle A$ is calculated by using the fact that the sum of the angles in any triangle is 180°. Thus,

$\angle A = 180^\circ - \angle J - \angle L = 180^\circ - 112.5^\circ - 92.5^\circ = 75^\circ.$

Final Answer:

• $\angle J = 112.5^\circ$,
• $\angle L = 92.5^\circ$,
• $\angle A = 75^\circ$.

Further Questions:

1. How do you apply the angle sum property of a triangle in this type of problem?
2. What happens if the triangle is not isosceles? How would you solve it then?
3. How can you check if your calculations are correct?
4. How can you prove that the base angles of an isosceles triangle are always equal?
5. Can you solve this type of problem if the base angles are given as expressions involving trigonometric functions?

Tip:

Always double-check the setup for congruence or symmetry when dealing with isosceles triangles; base angles are key!
