The three angles must add to 180. So x=180-(50+90)= 40 degrees.
no it cant. irrational number is any real number that cannot be expressed as a ratio.
Step-by-step explanation:
2x^2+7x-3=0
by doing splitting the middle term we get/ <u>using quadratic eq we get-</u>
Let's solve your equation step-by-step.
2x2+7x−3=0
For this equation: a=2, b=7, c=-3
2x2+7x+−3=0
Step 1: Use quadratic formula with a=2, b=7, c=-3.
x=
−b±√b2−4ac

Answer:
Step-by-step explanation:
Given
Represent Mai's distance as x and Clare's distance as y
farther than Mai
Required
Determine the relationship between both
farther than Mai
Substitute x for Mai
farther than x
Express as a mathematical expression:
Recall that Clare's distance is represented by y.
So, we have:
Hence, the relationship is:
