That's a triangle with angles 57 degrees and 95 degrees and we're asked for the third angle x.

The sum of a triangle angles is 180 degrees.

x + 57 + 95 = 180

x = 180 - 152 = 28

Check: 28 + 95 + 57 = 180 good

Answer: 28 degrees

In the figure, if m∠ABD = 120º, then m∠ADC = ___

Darya [45]

Okay first, use the sin rule ( $\frac{SinA}{a} = \frac{SinB}{b}$
so $\frac{Sin120}{35} * 30 = SinB$
sin^-1 this and you get 47.928....this is angle ADB
and as it is on a straight line, 180 - this angle gets ADC
180 - 47.928.... = 132.07

Based on the polynomial remainder theorem, what is the value of the function when x=−6 ?

Vaselesa [24]

ANSWER

$f( - 6) = 10$

EXPLANATION

The given function is
$f(x) = {x}^{4} + 8 {x}^{3} + 10 {x}^{2} - 7x + 40$

According to the remainder theorem,

$f( - 6) = R$
where R is the remainder when
$f(x)$

is divided by
$x + 6$

We therefore substitute the value of x and evaluate to obtain,

$f( - 6) = { (- 6)}^{4} + 8 {( - 6)}^{3} + 10 { (- 6)}^{2} - 7( - 6)+ 40$

$f( - 6) = 1296 + 8 ( - 216) + 10 (36) - 7( - 6)+ 40$

$f( - 6) = 1296 - 1728 + 360 + 42+ 40$

This will evaluate to,

$f( - 6) = 10$

Hence the value of the function when
$x = - 6$

is
$10$

According to the remainder theorem,
$10$
is the remainder when

$f(x) = {x}^{4} + 8 {x}^{3} + 10 {x}^{2} - 7x + 40$
is divided by
$x + 6$

Can someone explain how to find the answer to x

OLga [1]

Answer:

130

Step-by-step explanation:

X is the alternate corresponding angle to 50. 50+y=180

y=130

x and y = the same thing so 130 is the value of x
