We know that in an isosceles triangle the two base angles are equal so let's get the sum of both
54+54 = 108
So the vertex angle equals
180-108
72°
Answer:
m = 1/9
Step-by-step explanation:
Given:
x = 10
y = 8
x1 = 1
y1 = 9
Solution:
y - y1 = m ( x - x1 )
9 - 8 = m ( 10 - 1 )
1 = 9m
m = 1/9
Answer: -3.8
<em>In exact form: -19/5</em>
<em>Mixed fraction: -3 (and) 4/5</em>
Step-by-step explanation:
to add fractions, find the LCD or Lowest Common Denominator, then combine.
On her map 1 inch is equal to 20 miles.
5x=100

x=20
5 is for the 5 inches.
x is for the unknown.
100 is the 100 miles between the cities.
So the scale 1:20
120 x 0.20= 24. here you go
