24x^2 +25x - 47 53

----------------------- = -8x -3 - ---------------

ax-2 ax-2

add 53/ax-2 to each side

24x^2 +25x - 47+53

----------------------- = -8x -3

ax-2

24x^2 +25x +6

----------------------- = -8x -3

ax-2

multiply each side by ax-2

24x^2 +25x +6 = (ax-2) (-8x-3)

multiply out the right hand side

24x^2 +25x +6 = -8ax^2 +16x-3ax +6

24 = -8a 25 = 16 -3a

a = -3 9 = -3a

a = -3

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

$A+61.1\°+90\°=180\°$

$A=28.9\°$

Solve each quadratic equation. Show your work. 4x^2=100

ZanzabumX [31]

Hello there!

4x² = 100

We wanna start by dividing both sides by 4

4x²/4 = 100/4

x² = 25

Now we can take square root

x = +/-√25

x = 5 or x = -5

As always, it is my pleasure to help students like you!
