Answer:
its an acute angle
Step-by-step explanation:the only angle that small is an acute angle
Answer:
z = 105°
Step-by-step explanation:
See attachment.
1. The angle z plus 105° is equal to 180°, the straight line. Z must therefore be = 105°
2. Angles z and (15x + 45°) must be equal to 190°.
x is therefore equal to 4.
The perimeter is 41.7.
We first find the distance between each vertex using the distance formula:
We now find the perimeter by adding all of the side lengths:
14+7.81+19.92 = 41.73 ≈ 41.7
As 1 yard is equal to 3 feet , so 4 yard will be 12 feet !
so 13 foot > 4 yards
Answer:
Step-by-step explanation:
You know that ...
- cos(θ)² = 1 - sin(θ)²
- tan(θ) = sin(θ)/cos(θ)
- cosine is negative in the third quadrant (where π < θ < 3π/2)
Using what you know about the relationships of these trig functions, you can find ...
cos(θ)² = 1 - ((-√3)/2)² = 1 - 3/4 = 1/4
cos(θ) = -1/2 . . . . . negative square root of 1/4
__
tan(θ) = sin(θ)/cos(θ) = ((-√3)/2)/(-1/2)
tan(θ) = √3
