Answer:28
Step-by-step explanation:
The converse of an if statement is a statement in which the hypothesis and conclusion are switched.
<span>You will get into college if you work hard.
The "if" part is the hypothesis.
The "then" part is the conclusion.
Rewrite the original if statement in the if-then form:
If you work hard, then you will get into college.
The hypothesis is the if part: "you work hard"
The conclusion is the then part: "you will get into college"
To write the converse, switch the hypothesis and the conclusion.
If you get into college, then you worked hard.
This happens to be choice A.

Answer:
It is not a right triangles because 15^2 + 13^2 is NOT EQUAL to 19^2
let x, y, and z be the angles inside the triangle.
Law of cosines says:
19^2 = 13^2 + 15^2 - 2(13)(15)cos x
361 = 169 + 225 - 390 cos x
-33 = -390 cos x
-33/-390 = cos x
11/130 = cos x
x = inverse cosine (11/130)
= 85.14609471338569.....
Per law of sines:
sin x/19 = sin y / 13
(13/19)sinx = sin y
inverse_sine ( (13/19) sin x) = y
y = 42.9810733896016548....
Per law of sines
sin x/19 = sin z / 15
z = inverse_sine( (15/19) sin x)
= 51.8728352950227805....
So it is an acute triangle and yes, these angles add up to 180
