Step-by-step explanation:
An equilateral triangle has 3 equal sides and angles. Remember that <em>equil</em>ateral sounds like equal.
The interior angles of a triangle must equal 180 degrees.
- All 3 angles are the same.
- 180/3= 60
- All 3 angles in an equilateral triangle equal 60 degrees.
The question tells us the angle is equal to (4x-20).
- ∠= 60°
- ∠= (4x-20)°
So, by substitution, we can set 60 and (4x-20) equal to each other.
Now, solve for x by isolating the variable on one side of the equation.
20 is being subtracted from 4x and the inverse operation of subtraction is addition. Add 20 to both sides of the equation.
x is being multiplied by 4. The inverse operation of multiplication is division. Divide both sides of the equation by 4.
x is equal to 20 and choice 1 is correct.

Answer:
Diego is correct.
He has correctly divided 1 in groups of .
Step-by-step explanation:
The question 'How many groups of 5/6 are in 1?' means that we need to divided 1 into groups of .
When we form groups from a given total, we divided the total by the size of the group.
If we are dividing number of people in groups of
number of people, then the expression to find the number of groups formed can be given as:
⇒
For this question the data given is:
So, the number of groups formed can be given as:
⇒
When divisor is a fraction, then we multiply the reciprocal of the divisor with the dividend.
⇒
⇒
In order to convert fraction to mixed number we will divide numerator with denominator and then write the quotient as whole number, remainder as numerator and the denominator remains as it is.
On dividing 6 by 5, the quotient =1 and remainder =1. Thus the mized number is:
⇒
Thus, there are or
groups in 1. This matches with Diego's answer and hence he is correct.
