Solution:
1. Move all terms to one side
<span>25{x}^{2}+40x+16-28=0</span>
2. Simplify <span>25{x}^{2}+40x+16-28 to <span>25<span>x<span><span>2</span><span></span></span></span>+40x</span></span><span><span>−12</span></span>
<span>25{x}^{2}+40x-12=0</span>
3. Apply the Quadratic Formula<span>x=\frac{-40+20\sqrt{7}}{50},\frac{-40-20\sqrt{7}}{50}
</span>
4. Simplify solutions
<span>x=-\frac{2(2-\sqrt{7})}{5},-\frac{2(2+\sqrt{7})}{5}</span>
Done!
The answer would be
B) 1
hope this helps!

Answer:
Option A
Step-by-step explanation:
step 1
Find the value of b
we know that
----> by vertical angles
substitute the given values
solve for b
step 2
Find the measure of angle LQR
we know that
---> by supplementary angles (form a linear pair)
substitute the value of b
substitute in the expression above
