Find the area of a triangle when a = 19.2, A = 53.8°, and C = 65.4 Round to the nearest tenth.

Tju [1.3M]

Answer:

$A=181.0\ units^2$

Step-by-step explanation:

step 1

Find the length side c

Applying the law of sines

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

substitute he given values

$\frac{19.2}{sin(53.8^o)}=\frac{c}{sin(65.4^o)}$

solve for c

$c=\frac{19.2}{sin(53.8^o)}sin(65.4^o)\\\\c=21.6\ units$

step 2

Find the measure of angle B

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

$A+B+C=180^o$

substitute the given values

$53.8^o+B+65.4^o=180^o\\B=180^o-119.2^o\\B=60.8^o$

step 3

Find the area of the triangle

we know that

The area of the triangle applying the law of sines is equal to

$A=\frac{1}{2}(a)(c)sin(B)$

substitute the given vales

$A=\frac{1}{2}(19.2)(21.6)sin(60.8^o)\\\\A=181.0\ units^2$

ABCD is a parallelogram. AB>AD. Prove: m∠ADB>m∠BDC. Show your work (statement reason maybe?)

Gwar [14]

In the parallelogram ABCD, join BD.

Consider the triangle Δ ABD.

It is given that AB > AD.

Since, in a triangle, angle opposite to longer side is larger, we have,

∠ ADB > ∠ ABD. --- (1)

Also, AB || DC and BD is a transversal.

Therefore,

∠ ABD = ∠ BDC

Substitute in (1), we get,

∠ ADB > ∠ BDC.

Lilly and Rosie are sisters. The sum of their ages is 19 and the positive difference of their ages is 9. Set up a system of equa

likoan [24]

Answer:

Step-by-step explanation:

The sum of their age is 19.

This means that when you add their ages together, it will be 19.

L+R=19

The positive difference of their age is 9.

It tells you that Lily is the older child.

Since the difference is a positive number, that means it would be Lily's age minus Rosie's age since Lily is older.

L-R=9

Now you have 2 equations that can be used to find their ages.

Start with the first equation.

L+R=19.

Solve for L.

Subtract R on both sides.

L=19-R

Now use the substitution method (replacing or "substituting" L with 19-R) for the next equation.

L-R=9

(19-R)-R=9

19-2R=9

-2R=-10

R=5

Rosie's age is 5.

Rosie's age is 5. Now use the first equation to find Lily's age.

L+5=19

L=14.

Lily's age is 14.
