There are two other angles that could be present in the isosceles triangle.

The first angle is 80.

The second angle is 20.

We know this because all three angles in a triangle add up to 180 degrees.

An isosceles triangle has two sides that are the same length, and thus there are two equal angles.

80 + 80 = 160

180 - 160 = 20

Because of this, we know the measure of all three angles.

Humans have a normal body temperature of 98.6 F A temperature, x, that differs from normal by at least 2°F is considered unhealt
Romashka-Z-Leto [24]

Answer: 98.6 - x ≥ 2 or x - 98.6 ≥ 2  

Step-by-step explanation:

Since, the normal temperature = 98.6° F

Also, the temperature that differs from normal by at least 2°F is considered unhealthy.

If the temperature is x degree F,

Then, we have two conditions,

Condition 1 : x > 98.6,

The difference between 98.6 and x = x - 98.6

Then the inequality be,

x - 98.6 ≥ 2

Condition 2 : x < 98.6

The difference between 98.6 and x = 98.6 - x

Then the inequality be,

98.6 - x ≥ 2
