If angle U = 8x + 9 degrees, and angle W = 8x - 5 degrees, then the measure of angle U is ___ degrees.
PolarNik [594]

Answer:

m<U = 97^{o}

Step-by-step explanation:

From the given question, it can be observed that angles U and W are supplementary. These are angles that add up to 180^{o}.

So that;

<U + <W = 180^{o}

(8x + 9) + (8x - 5) = 180^{o}

16x + 4 = 180^{o}

16x = 180^{o} - 4

16 x = 176

x = \frac{176}{16}

  = 11^{o}

The measure of angle U = (8x + 9)

                                        = 8(11) + 9

                                        = 88 + 9

                                        = 97^{o}

Thus, the measure of angle U is 97^{o}.

Raise 2 to the 4th power, then add r to the result
Oxana [17]

Answer:

2⁴ + r

Step-by-step explanation:

Change the sentence into a expression.

Note that r is a variables.

"Raise 2 to the 4th power..." means 2 to the 4th power, or 2⁴.

"...then add r to the result" means: + r

Combine the two terms:

2⁴ + r is your answer.

~

Simplify if need be.

2⁴ = 2 * 2 * 2 * 2 = 4 * 4 = 16

r + 16 is your answer.

Factor the expression. Use the fundamental identities to simplify, if necessary.
Rasek [7]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x

Given

sin²x + 7cosx + 17

=1 - cos²x + 7cosx + 17

= - cos²x + 7cosx + 18 ← factor out - 1 from each term

= - (cos²x - 7cosx - 18)

Consider the factors of the constant term (- 18) which sum to give the coefficient of the cosx term (- 7)

The factors are - 9 and + 2, thus

= - (cosx - 9)(cosx + 2) ← in factored form

Surface Area using the net.
Hitman42 [59]

Step-by-step explanation:

step 1. very tough question! you need the slant height (h)

step 2. h = sqr(8^2 + 3^2) = sqr(73) sqr is the square root

step 3. SA = B + ph/2 where SA is the surface area, B is the base area, and p = the lateral perimeter

step 4. we will call the hypotenuse of the right triangle c

step 5. c = sqr(13^2 + 6^2) = sqr(205)

step 6. SA = (1/2)13(6) + (13 + 6 + sqr(205))sqr(73)/2

step 7. SA = 39+ (33.3178)(8.5440)/2 = 181.3336 cm^2.
