Answer:

137 degrees

Step-by-step explanation:

First thing, we know y is 43 because 43 degrees and y are vertical angles meaning they are congruent. (This is just a small part doesn't really do much though.)

Straight lines add up to 180 so simply just subtract 43 from 180.

180 - 43 = 137.

Therefore,

z = 137 degrees

Answer:

137

Step-by-step explanation:

Since angle Z and the angle of 43° are supplementary, the sum of them must equal 180. Therefore,

∠Z + 43 =180

∠Z = 137°

32 is 40% of what number

anzhelika [568]

40% = 40 / 100 = 0.4

32 is 40% of what

= 32 / 40

= 32 / 0.4

= 80

U can also use this equation to solve it.

32 = 40%x

Simplfy

= 32 = 2/5x

Flib the equation.

2/5x = 32

Multipy both sides by 5/2

(5/2) * 2/5x = (5/2) * 32

x = 80.

X^4 + x^3 + x^2 + x=0

kifflom [539]

X^4 + x^3 + x^2 + x = 0

x(x^3 + x^2 + x + 1) = 0

x[x^2(x + 1) + 1(x + 1)] = 0

x(x + 1)(x^2 + 1) = 0 ⇔ x = 0 or x + 1 = 0 or x^2 + 1 = 0

x = 0 or x = -1 or x^2 = -1 -false

Answer: x= 0 or x = -1.

Question 20: Please help what are sin x and cos x?

sweet [91]

Answer:

A is the correct answer.

Step-by-step explanation:

$\tan x = \frac{6}{8} = \frac{opposite \: side \: to \: \angle \: x}{adjacent \: side \: to \: \angle \: x} \\ \\ hypotenuse \\ = \sqrt{ {(opp. \: side)}^{2} + {(adj. \: side)}^{2} } \\ = \sqrt{ {6}^{2} + {8}^{2} } \\ = \sqrt{36 + 64} \\ = \sqrt{100} \\ = 10 \\ \\ \because \sin (x) = \frac{opposite \: side \: to \: \angle \: x}{hypotenuse} \\ \\ \huge{ \red{ \boxed{\therefore \: \sin (x) = \frac{6}{10}}}} \\ \\ \cos (x) = \frac{adjacent \: side \: to \: \angle \: x}{hypotenuse} \\ \\ \huge{ \purple{ \boxed{\therefore \: \cos (x) = \frac{8}{10} }}} \\$

Thus, option A is the correct answer.
