<h3>I'll teach you how to solve x^2 + 25 = 6x</h3>
----------------------------------------------------------
x^2 + 25 = 6x
Subtract 6x from both sides:
x^2+25-6x=6x-6x
Simplify:
x^2-6x+25=0
Solve with the quadratic formula:
For the quadratic equation of the form ax^2+bx+c=0 the solutions are:
1^x,2 = -b +,- sqrt b^2-4ac/2a
x= -(-6)+ sqrt (-6)^2-4*1*25/2*1 = 3+4i
x= -(-6)+ sqrt (-6)^2-4*1*25/2*1 = 3-4i
Your Answer Is x=3+4i, x= 3-4i
plz mark me as brainliest :)
Answer:
140 degree
Step-by-step explanation:
The sum of the interior angle measures in a regular polygon is 1260 degree.
(n-2)*180=1260
180n-360=1260
180n=1260+360
180n=1620
n=1620/180
n=9
Now, evaluate the measure of one of the interior angles of the polygon.
((9-2)*180)/9=140 degree.
We know that
scale factor=measure larger triangle/measure smaller triangle---->18/12
scale factor=1.5
so
measure larger triangle=scale factor*measure smaller triangle
for the leg in the smaller triangle equal to 5
measure larger triangle=1.5*5-----> 7.5
the answer is
7.5
10x - 3 = 5x + 2
5x = 5
x = 1
RT = ST = 10(1) - 3 = 7
answer
x = 1
RT = 7
ST = 7
