We have to calculate AC ( hypotenuse ):
AC² = 29² + 28²
AC² = 841 + 1444
AC² = 2285
AC = √2285
AC = 47.8
And for the angle C:
cos C = Adjacent / Hypotenuse
cos C = 38 / 47.8
cos C = 0.794979
∠ C = cos ^(-1) 0.794979
∠ C = 37.35° ≈ 37°
Answer: ∠ C = 37°.

Suppose log subscript a x equals 3, log subscript a y equals 7, and log subscript a z equals short dash 2. Find the value of the

enyata [817]

Answer:

Step-by-step explanation:

Given the following logarithmic expressions $log_ax = 3, log_ay = 7, log_az = -2$ , we are to find the value of $log_a(\frac{x^3y}{z^4} )$

$from\ log_ax = 3, x = a^3\\\\from\ log_ay = 7,y = a^7\\\\from\ log_az = -2, z = a^{-2}$ Substituting x = a³, y = a⁷ and z = a⁻² into the log function $log_a(\frac{x^3y}{z^4} )$ we will have;

$= log_a(\frac{x^3y}{z^4} )\\\\= log_a(\dfrac{(a^3)^3*a^7}{(a^{-2})^4} )\\\\= log_a(\dfrac{a^9*a^7}{a^{-8}} )\\\\= log_a\dfrac{a^{16}}{a^{-8}} \\\\= log_aa^{16+8}\\\\= log_aa^{24}\\\\= 24log_aa\\\\= 24* 1\\\\= 24$

Hence, the value of the logarithm expression is 24

X/8 - 1/2 = 6 its really hard and my teacher and I never went over it

Marina CMI [18]

Answer:

X = 52

Step-by-step explanation:

X / 8 - 1 / 2 = 6

X / 2³ - 1 / 2 = 6

X + 4( -1) / 2³ = 6

X - 4 = 48

X = 48 + 4

X = 52
