Answer:

x = 20 and y = 14.14213562 ( you can simplify it)

Step-by-step explanation

x = the opposite side divided by sin 45 ( the angle)

$10\sqrt 2$ / sin(45)

y = the opposite side divided by the adjacent side

$10\sqrt2$ / tan(45)

14.14213562

14.14

Answer:

Law of Sines

Step-by-step explanation:

Law of Sines: $\frac{A}{sina} =\frac{B}{sinb} =\frac{C}{sinc}$

Step 1: Solve for m∠B

$\frac{25}{sin36} =\frac{27}{sinx}$

25sinx = 27sin36°

sinx = 27sin36°/25

$x = sin^{-1}(\frac{27sin36}{25} )$

m∠B ≈ 39.4°

Step 3: Find m∠C

180 - (36 + 39.4)

180 - 75.4

m∠C = 104.6°

Without using your calculator, decide which of these is larger: log8 62 or log7 50. How confident are you of your answer? Explai

nataly862011 [7]

Answer:

Step-by-step explanation:

log8 62 = x1

8^x1= 62

8^2 =64 >62 so x1<2

log7 50=x2

7^x2=50

7^2=49<50 so x2>2

we have, x1<2 and 2<x2

x1<2<x2

x1<x2

log8 62<log7 50
