Answer:

$a=12$

Step-by-step explanation:

Pythagorean Theorem: $a^{2}+b^{2}=c^{2}$

In this case, a = 9, b = a, and c = 15.

$9^{2}+a^{2}=15^{2}$

$81+a^{2}=225$

The, we subtract 81 from both sides getting:

$a^{2}=144$ ,

Then, $a=12$

Write and solve an equation to find the complement of the angle that measure 42 degree

ser-zykov [4K]

Complementary angles add up to 90 degrees.

So we can write:

42 + x = 90

To solve, subtract 42 to both sides:

x = 48

So the complement of a 42 degree angle is a 48 degree angle.

Evaluate the expression. [(3–5)(34)]3 1 Innermost group, apply the product of powers: [3–1]3 2 Apply the power of a power: 3–3 3

Otrada [13]

Answer:

x=27

Step-by-step explanation:

To evaluate the expression: $[(3^{-5})(3^4)]^3$

Step 1: Innermost group, apply the product of powers ( $a^x \times a^y =a^{x+y}$

Therefore:

$(3^{-5})(3^4)=3^{-5+4}=3^{-1}$

We then have:

$=[3^{-1}]^3$

Step 2: Apply the power of a power

$[3^{-1}]^3=3^{-1 \times 3} =3 ^{-3}$

Step 3: Apply the negative exponent

$3 ^{-3} =\dfrac{1}{3^3}$

Step 4: Simplify

$\dfrac{1}{3^3}=\dfrac{1}{27}$

Therefore, the value of x in the simplified expression is 27.
