Mama L [17]

Answer:

Step-by-step explanation:

1/3 of 63= 21

and the reverse of 63 is 36

so 1/2 of 36 =18

so 21-18 =3

hence proven

Masteriza [31]

Answer:

m<1 = 57°

m<2 = 74°

Step-by-step explanation:

m<1 = 57° (alternate interior angles are congruent)

m<B + m<C + m<2 = 180° (sum of interior angles of a triangle)

57° + 49° + m<2 = 180° (substitution)

106° + m<2 = 180°

Subtract 106° from both sides

m<2 = 180° - 106°

m<2 = 74°

Item 4 In a circle with a radius of 36.9 m, an arc is intercepted by a central angle of 8π 5 radians. What is the arc length? Us

leva [86]

Answer:

The arc length is 185.39 meters.

Step-by-step explanation:

The arc length is calculated by the following expression:

$\Delta s = \Delta \theta \cdot r$

Where:

$r$ - Radius, measured in meters.

$\Delta \theta$ - Central angle, measured in radians.

If $r = 36.9\,m$ and $\Delta \theta =\frac{8}{5}\pi\, rad$ , the arc length, measured in meters, is:

$\Delta s = \frac{8}{5}\pi\cdot (36.9\,m)$

$\Delta s = \frac{8}{5}\cdot (3.14)\cdot (36.9\,m)$

$\Delta s \approx 185.386\,m$

$\Delta s \approx 185.39\,m$

The arc length is 185.39 meters.

Write the equation of the line<br> perpendicular to y = *x+7 with a<br> y-intercept of (0-1)

I am Lyosha [343]

Answer: y = -x - 1

<u>Step-by-step explanation:</u>

Use the Point-Slope formula: $y - y_1=m_{\perp}(x-x_1)$ where

(x₁ , y₁) is the given point (0, -1)
$m_{\perp}\ \text{is the opposite reciprocal slope of the given line}\implies m_{\perp}=-1$

Insert those values into the formula and solve for y:

y - (-1) = -1(x - 0)

y + 1 = -x

y = -x - 1
