Answers

Answer 1

Answer:

A= 3,B = 2

Hope it helps you

if yes mark me brainliest

Answer 2

Answer:

hence, a = 3

b = 2

Step-by-step explanation:

from the given pair of linear equation we get,

7a + 3b = 27 - ( 1 )

6a + 3b = 24 - ( 2 )

now, subtract equation 2 from equation 1

=》7a + 3b - 6a - 3b = 27 - 24

=》a = 3

now put the value of a in equation 1

=》7a + 3b = 27

=》( 7 × 3 ) + 3b = 27

=》21 + 3b = 27

=》3b = 27 - 21

=》b = 6 ÷ 3

=》b = 2

Step-by-step explanation:

The triangle is an isosceles triangle. Because the triangle is an isosceles triangle, the height and base of the triangle are equal to eachother.

a² + b² = c²

right now we have c² which is 7

a² + b² = 7

[tex] \frac{ \sqrt{7} }{2} [/tex]

because a² and b² are = to eachother

The points (-3, -3) and (5, r) lie on a line with slope 3/2
Find the missing coordinate r.

Answers

Answer:

The missing coordinate [tex]r[/tex] is 9.

Step-by-step explanation:

Given the points [tex]P(x,y) = (-3,-3)[/tex] and [tex]Q(x,y) = (5,r)[/tex], the slope of a line passing the two points ([tex]m_{PQ}[/tex]) is determined by equation of secant line:

[tex]m_{PQ} = \frac{y_{Q}-y_{P}}{x_{Q}-x_{P}}[/tex] (1)

[tex]m_{PQ} = \frac{r-(-3)}{5-(-3)}[/tex]

If we know that [tex]m_{PQ} = \frac{3}{2}[/tex], then the value of [tex]r[/tex] is:

[tex]\frac{3}{2} = \frac{r+3}{8}[/tex]

[tex]12 = r + 3[/tex]

[tex]r = 9[/tex]

The missing coordinate [tex]r[/tex] is 9.

Find cosθ, tanθ, and cscθ, where θ is the angle shown in the figure.
Give exact values, not decimal approximations.

Answers

Answer:

Cos(θ) = 7/√58 ; Tan(θ) = 3/7 ; Csc(θ) = √58/3

Step-by-step explanation:

First, let's solve for the hypotenuse by using the Pythagorean Theorem.

a² + b² = c²

⇒ 7² + 3² = c²

⇒ 49 + 9 = c²

⇒ 58 = c²

√58 = c

Now that we know the hypotenuse is √58, we can solve for the trig ratios.

Cos(θ) = adjacent/hypotenuse = 7/√58

Tan(θ) = opposite/adjacent = 3/7

Csc(θ) = hypotenuse/opposite = √58/3

Use synthetic division to solve

Answer:

∠QSR = 78°∠SQR = 51°

Step-by-step explanation:

The measure of an inscribed angle (QTR) is half the measure of the arc it intercepts. The measure of an arc is the same as the measure of the central angle it intercepts. So, we have ...

  ∠QSR = 2×∠QTR

  ∠QSR = 2×39°

  ∠QSR = 78°

__

Sides SQ and SR are radii of circle S, so are the same length. That means triangle QRS is an isosceles triangle and the base angles SQR and SRQ are congruent. The sum of angles in a triangle is 180°, so we have ...

  ∠QSR + 2(∠SQR) = 180°

  78° + 2(∠SQR) = 180° . . . . fill in the value we know

  2(∠SQR) = 102° . . . . . . . . . subtract 78°

  ∠SQR = 51° . . . . . . . . . . . . .divide by 2
