Answer:
o = 54
Step-by-step explanation:
The angle sum theorem tells you the sum of angles in a triangle is 180°. The definition of a linear pair tells you the two angles of a linear pair total 180°. Together, these relations tell you that an exterior angle of a triangle is equal to the sum of the remote interior angles.
In this geometry, the angle marked 78° is exterior to the left-side triangle. That means ...
78° = o° +24°
o° = 78° -24° = 54°
The value of 'o' is 54.

<em>Additional comment</em>
n° is the supplement of 78°, so is 102°.
m° is the difference between 102° and 22°, so is 80°.
Answer:
1/6
Step-by-step explanation:
gradient= change in y/ change in x
-4--5/2--4= 1/6
1/6 is the gradient
Answer:
n=19
Step-by-step explanation:
6n - 22 = 92
+ 22 +22

6 6
n = 19
Answer:
(1)
Step-by-step explanation:
Given
+ b = c ( subtract b from both sides )
= c - b ( multiply both sides by a to clear the fraction )
2x = a(c - b) ← distribute
2x = ac - ab ( divide both sides by 2 )
x = 
→ (1)
