Answer:
21
Step-by-step explanation:
When you subtract the length of the base from the length of the side, you get
(ax+9) - (4x+b) = (a-4)x +(9-b)
The answer is isosceles triangle
Answer:
method 2 use the radians sector area formula
<u>Given</u>:
Given that JKL is a right triangle.
The measure of ∠L is 90°
The length of JL = 24, LK = 7, and KJ = 25.
We need to determine the value of sine of ∠K.
<u>Value of sin ∠K:</u>
The value of sin ∠K can be determine using the trigonometric ratio.
Thus, we have;

Substituting
, the side opposite to angle K is JL and the hypotenuse is JK
Thus, we have;

Substituting JL = 24 and JK = 25, we get;

Simplifying, we get;



Thus, the measure of sine of ∠K is 73.74°
