Answer:
4x+50=90 being complementary
4x=90-50
x=40/4=10
value of x=10°
Answer:
Step-by-step explanation:
cosθ = ⅘
sin²θ = 1-cos²θ = 9/25
since θ is in quadrant I, sinθ = √(9/25) = ⅗
sin(2θ) = 2sinθcosθ = 2(⅗)(⅘) = 24/25
Answer:
i think its the first one but im not completely sure...
Answer:
5 packages
Step-by-step explanation:
One package of blackberries cost $3
Let x represent the number of packages that will cost $15
1 = $3
x= $15
3x= 15
Divide both sides by the coefficient of x which is 3
3x= 15/3
x= 5
Hence 5 packages of blackberries will cost $15
