To solve this, set up the equation, 90% of x being .9*x=57. Then, solve for x, x=57/.9=

=6.333
We have,
(2y)^3 × y^-1
Simplify the term (2y)^3
= 8y^3 × y^-1
Now, multiply the terms with the same base y by adding their exponents.
Note: Using exponent product rule x^y × x^z = x^(y+z)
= 8y^{3+(-1)}
= 8y^(3-1)
= 8y^(3-1)
= 8y^2
1cm is equal to 10mm, so 37cm is the same as 370mm
1cm is equal to 0.01m, so 37cm is the same as 0.37m
Answer:
x= 68.19°
Step-by-step explanation:
you can use inverse of cos(x)
(
) =68.19°
∴ x=68.19°
