Take the coefficient of the x-term, half it, then square that. add this to both sides
x² + 16x. coefficient of x is 16. half of 16 is 8. 8²=64
x² + 16x + 64 =64. this is your answer but to continue
x² + 16x + 64 = 64
(x+8)² = 64
x+8 = ✓64
x+ 8 = ±8
x = 0 or -16
Answer:
A
Step-by-step explanation:
Solution:
<u>We know that:</u>
- The base angles are equivalent.
<u>This means that:</u>
- This triangle is an isosceles triangle.
- The legs of the triangle are equivalent.
<em>Let's use Pythagoras theorem to find z.</em>
<u>Finding z using Pythagoras theorem.</u>
Thus, the value of z is 8.
