(n+7)(n-8)
Step-by-step explanation:
1. Find the Zeros



2. Factoring Trinomials



An obtuse triangle has those measurements
Answer: 82°
Step-by-step explanation:
<CDE = far arc - near arc / 2
i.e
<CDE = arcCBE - arcCE / 2
arcCE = 98°
arcCBE = 360° - 98° = 262°
<CDE = 262° - 98° / 2
<CDE = 164 / 2
<CDE = 82°
Therefore the measure of < CDE is 82°
In exponential form, it would be xy^2z^3
