Step-by-step explanation:

Tangent is calculated as the length of the opposite side of an angle divided by the adjacent side of that angle.

The opposite of theta is 4, while its adjacent side is 2

tan theta = 4/2 = 2

Find all the missing dimensions when a=9, b=13, c=64°

DerKrebs [107]

Answer:

Part 1) $c=12.14\ units$

Part 2) $m\angle A=41.78^o$

Part 3) $m\angle B=74.22^o$

Step-by-step explanation:

step 1

Find the measure of side c

Applying the law of cosines

$c^2=a^2+b^2-2(a)(b)cos(C)$

we have

$a=9\ units\\b=13\ units\\C=64^o$

substitute

$c^2=9^2+13^2-2(9)(13)cos(64^o)$

$c^2=81+169-234cos(64^o)$

$c^2=250-234cos(64^o)$

$c^2=147.4212$

$c=12.14\ units$

step 2

Find the measure of angle A

Applying the law of sines

$\frac{a}{sin(A)}=\frac{c}{sin(C)}$

substitute the given values

$\frac{9}{sin(A)}=\frac{12.14}{sin(64^o)}$

solve for sin(A)

$sin(A)=\frac{sin(64^o)}{12.14}(9)$

$sin(A)=0.6663$

$m\angle A=sin^{-1}(0.6663)=41.78^o$

step 3

Find the measure of angle B

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

$m\angle A+m\angle B+m\angle C=180^o$

substitute the given values

$41.78^o+m\angle B+64^o=180^o$

$m\angle B+105.78^o=180^o$

$m\angle B=180^o-105.78^o$

$m\angle B=74.22^o$

Find the largest consecutive integers whose sum is less than 46

zmey [24]

The largest consecutive integers whose sum is less than 46 are x= 21 and x+1=22

Step-by-step explanation:

Let the integers be:

x and x+1

The sum of these integers is less than 46

$x+(x+1)$

Solving and finding value of x:

$x+(x+1)$

So, the integers will be less than 22.5

The largest numbers are: 21 and 22

So, the largest consecutive integers whose sum is less than 46 are x= 21 and x+1=22
