Answer:
The length of b is
.
Step by step explanation:
Given information: In ΔABC, ∠A =∠C, ∠B = ß (where ß is an acute angle), and BC = x.
Since two angles are same therefore triangle ABC is an isosceles triangle and side AB and BC are congruent.

According to Law of cosine





Therefore the length of b is
.

Answer: The hypotenuse is 53 (approximately)
Step-by-step explanation: In this question we shall apply the Pythagoras theorem which states that;
AC^2 = AB^2 + BC^2
Where AC is the hypotenuse and AB and BC are the two other sides. Having been given that the two other sides are 36 and 39 units respectively, the hypotenuse is now,
AC^2 = 36^2 + 39^2
AC^2 = 1296 + 1521
AC^2 = 2817
Add the square root sign to both sides of the equation
AC = 53.0754
Therefore the hypotenuse is approximately 53 units.
Answer:
-26 is the y-intercept
Step-by-step explanation:
since you already have the slope solved, you just have to plug in one of the two coordinate pairs. i plugged it (4,6) since it didnt have any negatives to work with. 6 should be where y is and 4 is x. you now should solve it as a normal equation. it gave me -26.
