Answer: 19.93
Step-by-step explanation:
Answer:
The answer is A
Step-by-step explanation:
If a triangle is made up of side lengths a, b and c
Given that c is the longest side length of the triangle,
The Pythagorean theorem can be used to tell if the triangle
is obtuse, acute or right
In an obtuse triangle,
a^2 + b^2 < c^2
In an acute triangle,
a^2 + b^2 > c^2
In a right angled triangle,
a^2 + b^2 = c^2

Answer: x = 2 and z=78
Step-by-step explanation:
Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure). Z is Opposite to 78 angle, so z=78.
Adjacent angles add up to 180 degrees, and 78 and (5x + 92) are adyacents so:
5x + 92 + 78 = 180
5x + 170 = 180
5x = 180 - 170
5x = 10
x = 10/5
x = 2
