Rewrite it in the form a^2 + 2ab + b^2, where a = y^2 and b = 6

(y^2)^2 + 2(y^2)(6) + 6^2

Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2

(y^2 + 6)^2

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

$A+61.1\°+90\°=180\°$

$A=28.9\°$

Answer:

$(m^{4} + 5) - n^{3}$ = 85

Step-by-step explanation:

$(m^{4} + 5) - n^{3}$ given m = - 2, and n = -4

Substitute the given values into the polynomial expression:

$(m^{4} + 5) - n^{3}$

$[(-2)^{4} + 5] - (-4)^{3}$

= (16 + 5) - (-64)

= 21 + 64

= 85

Therefore, the correct answer is 85.
