Step-by-step explanation:
Answer:
36 divided by 2 is 18 = plus 1p
Step-by-step explanation:
Answer:
We have sinθ = 12/13
The method here is to figure out the value of θ
Using a calculator sin^(-1)(12/13) =67.38°
67.38° is in quadrant 1 so we must substract 67.38° from 180° wich is π
- 180-67.38= 112.61° ⇒ θ= 112.61°
Now time to calculate cos2θ and cosθ using a calculator
- cosθ = -5/13
- cos2θ = -0.7
The values we got make sense since θ is in quadrant 2 and 2θ in quadrant 3
Using the distance formula,


Since ABCD has two pairs of opposite congruent sides, it is a parallelogram.
Answer:
the connection is at 4 on x axis and 5 on y axis, so the solutions are x=4; y=5
