If z=14 and x=83 , then what is the value of y?

Mathematics

LenaWriter [7]3 years ago

Answer:

y = 152

Step-by-step explanation:

The chord- chord angle x is half the sum of the arcs intercepted by the angle and its vertical angle, that is

$\frac{1}{2}$ (y + z) = 83 ( multiply both sides by 2 to clear the fraction )

y + z = 166

y + 14 = 166 ( subtract 14 from both sides )

y = 152

Find the exact value of the given expression.<br> sin(2cos^-1(5/13))

xeze [42]

Answer:

+120/169 or -120/169

Step-by-step explanation:

let $cos^{-1}[\frac{5}{13} ] = \alpha$

where, alpha is some angle that satisfies the assumed condition.

so, $cos\alpha= 5/13$

[ taking cos to the other side or applying cos on both sides]

now, substitute this in the given expression

$sin(2cos^-1(5/13)) = sin(2\alpha )$

as sin $\beta$ = $+ or -\sqrt{1-(cos\beta) ^{2}$

[by general trigonometry formula: $cos^{2}[\beta] +sin^{2}[\beta]=1$ ]

so if $cos\alpha= 5/13$ , we can get sin $\alpha$ from the above formula as + or - 12/13

(because, after taking square root on both sides we keep + or -]

as, sin $2\beta = 2*sin[\beta ]*cos[\beta ]$

[by general trigonometry formula]

here, now $sin[2\alpha ]=2*(+or- 12/13)*5/13\\$

so, the final value can be 120/169 or -120/169.

Can an area of a polygon be zero?<br><br> true or false

Nata [24]

False. If the area is 0 that means there is nothing there, therefore the area of a polygon cannot be zero.

Two functions are shown below.

dimaraw [331]

Answer:

x=5

Step-by-step explanation:

Ok so put them equal to each other

2x+12=3x+7

subtract 12 from both sides

2x=3x-5

subtract 3x from both sides

-x=-5

divide both sides by -1

x=5
