U have an equilateral triangle where all angles are equal to 60 degrees
7x + 4 = 60
7x = 60 - 4
7x = 56
x = 56/7
x = 8 <==
and if u wanted to find y, u would set it up like this : 8y + 12 = 60 and solve for y
Step-by-step explanation:
in two no. question what is in the power of X is that 3 or 5

Answer:
x = √(28), or x = 5.292
Step-by-step explanation:
First you distribute the square to the values inside of the parentheses. so it ends up looking like this
5(x^2 - 25) - 9 = 6
add 9 to both sides
so its 5(x^2 - 25) = 15
Then distribute the multiplication of 5 to the contents within the parentheses
so it would be 5x^2 - 125 = 15
add 125 to both sides
you get 5x^2 = 140
divide by 5 on both sides
you get x^2=28
then, take the square root of both sides to reverse the square
√(x^2)=√(28)
and in the end you get x=5.292
but √(28) will probably be fine if your teacher doesn't want u to solve for that kind of stuff.
