Answer:
x=2
Step-by-step explanation:
6x+7x−3x=13+7
10x=20
x=20/10
x=2
Answer:
37 books
Step-by-step explanation:
Answer:
root 24+12 is root 36 which is equal to 6
4 root of 6 is 36 the power of 2 which is equal to 36
5 the power of 2 is 25
then when we multiple 6x36x25
it's 5400
Step One
Find z
All triangles have 180 degrees. No exceptions.
z + 47 + 90 = 180 combine like terms on the left.
z + 137 = 180 subtract 137 from both sides
z = 180 - 137
z = 43 degrees.
Step Two
Use the sine function to find y
Sin(43) = opposite side / hypotenuse
opposite side = 35
sin(43) = 35 / hypotenuse
hypotenuse = 35 / sin(43)
y = 35/0.6820
y = 51.32
Solve using cos(x)
Note this problem could have been done in a shorter way.
Cos(47) = adjacent / hypotenuse.
hypotenuse = adjacent / cos(47)
y = 35 / cos(47)
y = 35 / 0.6820
y = 51.32 Both answers agree. It is a good thing to know how to do this question both ways.
