Complementary angles add up to 90°
∠BDC + ∠CDA = 90°
Answer: ∠BDC
Cot x = cos x csc x
1/tan x = cosx (1/sin x)
1/(sin x / cos x) = cos x / sin x
cos x / sin x = cos x / sin x
The domain of validity is all real number values of x except for sin x = 0.
180-130=50
180-96=84
angles in a triangle add up to 180
50+84=134
180-134=46
x=46 degrees
Answer:
Willie will run 7 miles in 28 minutes.
Step-by-step explanation:
X-6=1/3x( solve equation)
x-1/3x=6
0.7x=6
x=6/0.7
x=8.5 ( i guess its like this)
