Answer:
sin(B) = 
cos(B) = 
tan(B) = 
Step-by-step explanation:
I always find it easiest to model out the triangle: Angle B will be at the converging point of a and c.
Using SOH CAH TOA, we know that the Sin of an angle will be its opposite over hypotenuse. The opposite is 15, and the hypotenuse is 17.
So is the sin of B.
We also know that the cosine of B will be it's adjacent over hypotenuse. The adjacent is 8 and the hypotenuse is 17, so
Lastly, we know the tangent of B will be it's opposite over adjacent. The opposite of B is 15, and it's adjacent is 8, so
is the tangent of B.
Hope this helped!
Answer:
2/6
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
2(4x+1) + (5x-4) = 180
13x-2=180
x = 182/13 = 14
It is an isoceles triangle, so D = E
F = 66
D = E = 57
Hello!
To find how much chocolate Adi and Suresh receives, you need to convert the percentage to a decimal, then you multiply that decimal by the total number of chocolates, which is 20.
To convert percentages to decimals, divide the percentage by 100, and remove the percentage.
60% / 100 = 0.60
20% / 100 = 0.20
Then, we multiply 0.60 and 0.20 by 20.
0.60 x 20 = 12
0.40 x 20 = 8
Therefore, Adi gets 12 chocolates and Suresh gets 8 chocolates.
Answer:
7x - 2
Step-by-step explanation:
let x be the number of bags of chips, then
3x is the number of bags of pretzels ← 3 times the number of bags of chips
3x - 2 is the number of bags of nachos ← 2 less than bags of pretzels
total snacks bought = x + 3x + 3x - 2 = 7x - 2
