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°
The area of the triangle below is 7.5 units
Answer:
D but see below.
Step-by-step explanation:
It can be factored if you are allowed to use square roots.
(p + 5√5)(p - 5√5)
Usually, you are not allowed to do that. Usually you must be working with whole numbers or rational well behaved fractions.
I think, given the above comment, the answer is D
