Let, the number be "x"
Now,
according to the question,
4x -8 = x -23....................This is your equation.
Now solving it,
4x - 8 = x - 23
4x - x = -23 + 8
3x = -15
x = -15 / 3
x = -5
Checking the answer,
4 (-5) - 8 = (-5) - 23
-20 - 8 = -5 - 23
-28 = -28......................................true
Answer:25°
Step-by-step explanation:
One angle =130°
An isosceles triangle has two equal angles
Sum of angles in a triangle is 180°
Let the other two angles in The isosceles triangle be y°
130+y+y=180
Collect like terms
y+y=180-130
2y=50
Divide both sides by 2
2y/2=50/2
y=25
There other two angles in The isosceles triangle are 25° each
Well, Mathematics can enhance your analytical and problem-solving skills, expands the mind to handle difficult or unfamiliar tasks, and also promotes cautious and careful thinking. Once you know what the words mean you'll be able to write different variable expressions. Like I said it enhances our minds and helps think and solve probelms.
Answer:
Step-by-step explanation:
Diameter= 6 ft
