Answer:
65
Step-by-step explanation:
$5'+&6$7::$6&-9+_27-8$
15-t + 8t = -13
15 + 7t = -13
7t = -13-15
7t = -28
t = -4
4a + 11-a = 2
3a = 2-11
3a = -9
a = -3
A should be correct. hope this helped

Answer:
The given triangle is an obtuse angled triangle.
Step-by-step explanation:
The measures of the given angle are:
∠1 = 17°, ∠2 = 103° and ∠3 = 60°.
OBTUSE ANGLE: The angle whose measure is more than 90° and less than 180° is an obtuse angle.
Now, Here, in the given triangle, ∠2 = 103° is an obtuse angle.
The triangle with a obtuse angle is known as an Obtuse Angled Triangle.
Hence, the given triangle is an obtuse angled triangle.
