There are two "special" right triangles:
isosceles 45°-45°-90° triangle with sides in the ratios 1 : 1 : √2
30°-60°-90° triangle with sides in the ratios 1 : √3 : 2
These side lengths give rise to the trigonometric ratios shown below for angles with 30°, 45°, or 60° as reference angles.

Answer:
t = 17.3
Step-by-step explanation:
The following data were obtained from the question:
Angle T = 87°
Opposite T = t =?
Opposite V = v = 14
Opposite U = u = 11
The value of t can be obtained by using cosine rule formula as shown below:
t² = v² + u² – 2vu CosT
t² = 14² + 11² – 2 × 14 × 11 × Cos87°
t² = 196 + 121 – 308 × Cos87°
t² = 317 – 16.119
t² = 300.881
Take the square root of both side
t = √300.881
t = 17.3
Therefore, the value of t is 17.3
Answer:
540°

Step-by-step explanation:
<u>Step 1: Define</u>
We are given a 5-sided polygon (irregular pentagon)
n = 5
<u>Step 2: Find Sum</u>
- Substitute in <em>n</em> [Sum of Angles]: 180(5 - 2)°
- (Parenthesis) Subtract: 180(3)°
- Multiply: 540°
The expression coud be re written:
12x²y/2xy + 6xy/2xy + 4x²/2xy . Simplify numerator & denominator whenever it is possible:
6x-3+2x/y
