Answer to the question

Zepler [3.9K]

Answer:

x = 23

Step-by-step explanation:

AE = EC

so, 5x + 3 = 118

5x + 3 = 118

Bring +3 to the other side so -3

5x = 118 - 3

5x = 115

Bring 5 to the other side so:

x = 115 ÷ 5

x = 65

What is the exact value of sin(157.5°)?

goldfiish [28.3K]

Answer:

$\frac{\sqrt{2 - \sqrt{2} } }{2}$

Step-by-step explanation:

$sin ^{2}$ $(157.5°)$ $=$ $1/2(1 - cos(2*157.5))$

$==> 1/2(1 - cos(315))$

$==> 1/2(\sqrt{2} /2)$

$==> (2 - \sqrt{2} ) / 4$

sin(157.5°) is in quadrant ll , meaning sin(157.5°) is greater than 0 , so we take positive square root of sin(157.5°)

sin(157.5) = $\frac{\sqrt{2 - \sqrt{2} } }{2}$

Write the point -slope form of the equation of each line given the slope and y-intercept. Slope=(2/3), y-intercept =0

MakcuM [25]

Answer:

$\large\boxed{y-0=\dfrac{2}{3}(x-0)\to y=\dfrac{2}{3}x}$

Step-by-step explanation:

The point-slope form of ane equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point on a line

We have:

$m=\dfrac{2}{3}$

y-intercept is for x = 0.

Therefore, if y-intercept = 0, then we have the point (0, 0).

$y-intercept=0\to(0,\ 0)$

Substitute:

$y-0=\dfrac{2}{3}(x-0)\to y=\dfrac{2}{3}x$
