Answer:
x = 31.5
Step-by-step explanation:
The triangle on the left has 2 congruent sides and is therefore isosceles.
Thus the 2 base angles are congruent with measure
= 
= 63
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
The triangle on the right is also isosceles with base angles of measure x
63° is an external angle of the triangle on the right, thus
x + x = 63
2x = 63 ( divide both sides by 2 )
x = 31.5
C doesn't have an inverse.
Answer:
+4
Step-by-step explanation:
Subtract a number from the number after it.
6 - 2 = 4
Answer:
(-6,2)
Step-by-step explanation:
Answer:
A. Perpendicular
Step-by-step explanation:
Lines are perpendicular if their slopes are opposite reciprocals of each other. Opposite, meaning if positive, the other slope is negative, and if negative, the other slope is positive. Reciprocal meaning, the number is flipped upside down, turning fractions into whole numbers and vice versa.
1/9
-1/9
-9
The slopes are perpendicular
