What is the easiest to understand formula for solving 30 60 90 special right triangles?

Marianna [84]

Step-by-step explanation:

30°, 60°, 90° triangle theorem states that:

Lengths of the side opposite to 60° angle is equal to root 3 upon two times of the length of hypotenuse and side opposite to 30° angle is equal to 1 upon two times of the length of hypotenuse.

Mathematically it can be expressed as:

$Length \: of \: sides \: opposite \: to \: 60 \degree \: \\ angle \\ = \frac{ \sqrt{3} }{ {2} } \times length \: of \: hypotenuse.\\\\Length \: of \: sides \: opposite \: to \: 30 \degree \: \\ angle \\ = \frac{1}{ {2} } \times length \: of \: hypotenuse.\\\\$

The normal body temperature of a camel is 37°C. This temperature varies by up to 3°C throughout the day. Write and solve an abso

uysha [10]

The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3 AND ( - t - 37 ) ≤ 3
t ≤ 3 + 37 - t + 37 ≤ 3
t ≤ 40 - t ≤ 3 - 37
 - t ≤ - 34 / *( - 1 )
 t ≥ 34
Answer t ∈ [ 34°C, 40° C ].
