Answer:
the missing angle is 148°
Step-by-step explanation:
the sum of all exterior angles of a triangle are 360°
so, 360-138-74 = 148°
Answer:
The answer is 5.71428571
Step-by-step explanation:
The lengths of the sides of the triangle are 8, 8, 20
Explanation:
Given that the perimeter of an isosceles triangle is 36 inches.
The base of the triangle is
times longer than each of its legs.
We need to determine the lengths of the sides of the triangle.
<u>Lengths of the sides:</u>
Let x denote the lengths of the sides of the triangle.
The base of the triangle is given by

Perimeter of the isosceles triangle = Sum of the three sides of the triangle.
Thus, we have,



Thus, the length of the sides of the isosceles triangle is 8 inches.
Base of the triangle = 
Hence, the three sides of the isosceles triangle are 8, 8, 20
Answer:
Options B and C
Step-by-step explanation:
Here, we want to select the set of points in which the difference between their vertical distance is less than 6 units
Let us consider the options one after the other;
A. 1-4-(-5) = 6.4
B. 0.2-(-1.6) = 0.2 + 1.6 = 1.8
C. 2.5-(-3) = 5.5
D. 7-(-1) = 7 + 1 = 8
So we can see that the options B and C are separated by vertical distance less than 6
