The answer would probably be D because you don't know what x is.
Answer:
False i think
Step-by-step explanation:
Make an equation system based on the problem
eg. a is the first number and b is the seond number
An equation for "<span>The sum of two numbers is 53" is
</span>⇒ a + b = 53
An equation for "<span>twice the first number minus three times the second number is 26"
</span>⇒ 2a - 3b = 26
<span>
Solve the equations by elimination and subtitution method
Eliminate a to find the value of b
a + b = 53 (multiplied by 2)
2a - 3b = 26
--------------------------------------
2a + 2b = 106
2a - 3b = 26
------------------- - (substract)
5b = 80
b = 80/5
b = 16
Subtitute the value of b to one of the equations
a + b = 53
a + 16 = 53
a = 53 - 16
a = 37
The numbers are 16 and 37</span>
Answer:
the perimeter is 87
Step-by-step explanation:
Given:
A figure of a triangle.
To find:
The exterior angles.
Solution:
If one side of a triangle is extended, then the angle between the extended side and the other side of triangle is known as exterior angle of the triangle.
In the given figure angle 1 and angle 5 are interior angles because they are inside the circle.
In the given figure angles 2,4,6 are exterior angles because they are lie between the extended side and the other side of triangle.
Angle 3 is the angle between two extended sides. So, it is neither interior not exterior angle of the triangle.
Only 2,4,6 are the exterior angles of the given triangle. Therefore, the correct options are C, D, E.
