Solve the right triangle, ΔABC, for all the missing side and angles to the nearest tenth given sides a = 10.6 and b = 19.2.

Aliun [14]

Answer:

Part 1) $c=21.9\ units$

Part 2) $B=61.1\°$

Part 3) $A=28.9\°$

Part 4) $C=90\°$

Step-by-step explanation:

step 1

Find the length side c

Applying the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$

substitute the given values

$c^{2}=10.6^{2}+19.2^{2}$

$c^{2}=481$

$c=21.9\ units$

step 2

Fin the measure of angle B

we know that

In the right triangle

$tan(B)=b/a$

substitute the given values

$tan(B)=19.2/10.6$

$B=arctan(19.2/10.6)=61.1\°$

step 3

Find the measure of angle A

we know that

The measure of interior angles in a triangle must be equal to 180 degrees

∠A+∠B+∠C=180°

Remember that in a right triangle the measure of angle C is 90 degrees

we have

$B=61.1\°$

$C=90\°$

substitute

$A+61.1\°+90\°=180\°$

$A=28.9\°$

Find the area of the rhombus

MAXImum [283]

<h3> Solution :-</h3>

Area of rhombus :-

$\bf \star \: \: \boxed{ \bf \dfrac{d_{1}d_{2}}{2} }$

$\sf \longrightarrow d_{1} = 4 \sqrt{3} + 4 \sqrt{3} = 8 \sqrt{3}$

$\sf \longrightarrow d_{2} = 4 + 4 = 8$

Area of rhombus :-

$: \implies \sf \dfrac{8 \sqrt{3} \times 8 }{2}$

$: \implies \sf 8 \sqrt{3} \times 4$

$: \implies \bf 32 \sqrt{3} \: {m}^{2}$

Dexter was asked to mix the punch for his sister’s birthday party. He has to figure out how much water and pure concentrate to a

Zigmanuir [339]

Answer:

6 liters

Step-by-step explanation:

Let x represent the amount of pure concentrate used to make the punch. Then the total amount of concentrate in the punch is ...

0.20·10 +1.00x = 0.50(10+x)

x +2 = 0.5x +5 . . . . . eliminate parentheses

0.5x = 3 . . . . . . . . . . .subtract 2+0.5x

x = 6 . . . . . . . . . . . . . multiply by 2

6 liters of pure concentrate must be added to make a 50% punch.
