Answer:

See explanation

Step-by-step explanation:

(4)

Using the sine ratio in the right triangle

sinΘ = $\frac{opposite}{hypotenuse}$ = $\frac{7}{9}$ , thus

Θ = $sin^{-1}$ ( $\frac{7}{9}$ ) ≈ 51.1°

(5)

Using the tangent ratio in the right triangle

tanΘ = $\frac{opposite}{adjacent}$ = $\frac{4}{5}$ , thus

Θ = $tan^{-1}$ ( $\frac{4}{5}$ ) ≈ 38.7°

What is the slope of the line that passes through the given points: (-2,8) and (4,6)?

Let's find the slope :

taking :

$y_2 = 6$

$y_1 = 8$

$x_2 = 4$

$x_1 = - 2$

now, we know the formula to find the slope, that is :

$\dfrac{y_2 - y_1}{x_2 -x_1 }$

$\dfrac{6 - 8}{4 - ( - 2)}$

$\dfrac{ - 2}{ 6}$

$- \dfrac{ 1}{3}$

For what value of x is sin x = cos 19º, where 0°< x < 90°?

KonstantinChe [14]

Answer:

71°

Step-by-step explanation:

The cosine of an angle is equal to the sine of its complement:

cos(19°) = sin(90° -19°) = sin(71°)

Comparing to the given expression, we see that x = 71°.

GEOMETRY URGENT HELP NEEDED

son4ous [18]

First we find the measurement of dark dot .

ANd for that we have to use the formula of the angle formed by the intersection of chord .

Let the dark dot be t.

So we have

$t =\frac{1}{2} (96+66)=81$

t and z are linear pair and sum of angles of linear pair =180 degree.

So we get

$t+z=180 \\ 81+z =180 \\ z = 180-81 =99 degree$

Please solve thanks lovee

Answer:

m∠1 = 93.5°

Step-by-step explanation:

By theorem of intersecting chords inside a circle,

If two chords intersect inside a circle, angle formed between the chords measure half the sum of the measures of the intercepted arcs.

m∠1 = $\frac{1}{2}(92+95)$

= $\frac{187}{2}$

= 93.5°

Therefore, measure of angle 1 is 93.5°.
