Find the missing side or angle. round to the nearest tenth.

3)

x = 5.3

4)

<A = 22.6°

<B = 67.4°

Step-by-step explanation:

Tan(A) = 5/12

<A = 22.6°

Tan(B) = 12/5

<B = 67.4°

Or you can find <B = 90 - <A) = 90° - 22.6° = 67.4°

3)

tan(24) = x / 12

x = 12 * tan(24)

x = 12 * 0.4452

x = 5.3

your answer is the frist one

hop i

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
