Easy, it's on a 90 degree angle, split in half, with one angle being 22 degrees. So, you do 90-22 and get 68 degrees!

The answer you are looking for is 68 Degrees because 90 degrees minus 22 equals 68 and that is x.

Help help im so confused as per usual
Alik [6]

Answer:

Step-by-step explanation:

a. HM = 14

HN = 21

HK = 10.5

Based on intersecting chords theorem,

HK*HJ = HM*HN

10.5*HJ = 14*21 (Substitution)

HJ = 294/10.5

HJ = 28

b. VC = 7.2

VG = 12

Based on tangent-secant theorem, thus:

VD*VC = VG²

VD*7.2 = 12²

VD = 144/7.2

VD = 20

Therefore,

CD = VD - VC

CD = 20 - 7.2

CD = 12.8

Help please !! <br><br> What is the measure of &lt;8
Damm [24]

Answer:

C. 39

Step-by-step explanation:

m∠3 ≅ m∠5

4x - 7 = 6x - 81

-7 = 2x - 81

74 = 2x

37 = x

m∠5 = 6(37) - 81 = 141

m∠8 = 180 - 141 = 39

I’m not sure if it would be A or B, does anyone know?
KengaRu [80]
B.  It is vertically stretched by a factor of 4.  If you had x^2 versus 4x^2, when x is positive and increasing, 4x^2 is increased by 4 for every value of x.

random sample has been taken from a normal population and two confidence intervals constructed using exactly the same data. The
Zepler [3.9K]

The sample mean of the random sample is 50

The margin of error (E) is the amount of error allowed in the random sample.

The confidence interval (CI) is given by:

CI = μ ± E = (μ - E, μ + E)

Given a confidence interval of (38.02, 61.98), hence:

μ - E = 38.02     (1)

μ + E = 61.98     (2)

Hence solving equations 1 and 2 simultaneously gives:

μ = 50, E = 11.98

Hence the sample mean of the random sample is 50

Answer and Step-by-step explanation:

7.

The <u>volume</u> of a cylinder is \pi r^{2} h, in which:

r = radius

h = height

d = 2 × r

\pi will equal 3.14.

Plug it in to the equation.

V = (3.14)(12^{2} )(42)\\\\\\\\V = (3.14)(144)(42)\\\\\\\\V = (452.16)(42)\\\\\\\\V = 18990.72cm^3

18990.72 cm^3\\ is the answer. (2nd Answer choice)

8.

x = -2

Expression is:

5 - x^2

Plug -2 in for x.

5 - (-2)^2\\\\\\\\5 - 4\\\\\\\\1

1 is the answer choice. (1st Answer choice).
