Answer:

∠V = 32°

Step-by-step explanation:

VW = UV

⇒ Isosceles triangle. So, the angles opposite sides are equal.

∠W = ∠U

∴ ∠W = ∠U = 74°

<h3>Angle sum property</h3>

Sum of all angles of triangle = 180

74 + 74 + ∠V = 180

148 + ∠V = 180

∠V = 180 - 148

∠V = 32°

Could someone please answer question b) ii) ? The question is on the attached image.

mel-nik [20]

Answer:

b) i) Curve A

ii) - 1.75

iii) x = 1 - √5 or x = 1 + √5

Step-by-step explanation:

b) i) We are given a function y = x² - 2x - 3 and the graph of this function is also shown in the side diagram.

The equation can be rearranged to y = (x - 1)² - 4

⇒ (x - 1)² = y + 4

Therefore, this is an equation of a parabola having the vertex at (1,-4) point and its axis is parallel to the positive y-axis.

So, the curve A represents the equation given. (Answer)

ii) Now, at x = 2.5, f(x) = 2.5² - 2 × 2.5 - 3 = - 1.75 (Answer)

iii) When y = 1, then x² -2x - 3 = 1

⇒ x² - 2x - 4 = 0

⇒ (x - 1)² - 5 = 0

⇒ (x - 1)² - (√5)² = 0

⇒ (x - 1 + √5)(x - 1 - √5) = 0

⇒ x = 1 - √5 or x = 1 + √5 (Answer)

PLEASE HELP DUE IN 40 MINS!! Using the Law of Sines, find the exact answer for x.

Savatey [412]

Answer:

Step-by-step explanation:

Sin(30) / X = Sin(45) / 12

use algebra to isolate X

1 / X = [ Sin(45) / 12 ] / Sin(30)

flip both sides

X = Sin(30) / [Sin(45) /12 ]

invert the denominator on the right side

X = Sin(30) * 12/ Sin(45)

Do you know what Sin(30) is off the top of your head?

and also Sin(45) ?

these are worth remembering... and you can b/c they are just

sin(0) = 0/2

sin(30) = 1 / 2

sin(45) = $\sqrt{2}$ /2

sin(60)= $\sqrt{3}$ / 2

sin(90) = $\sqrt{4}$ / 2 (aka 1)

note the numerators just counts up 0, 1, 2, 3, 4 :)

Cos works the same way but counts from 90° back to 0 but exactly like sin other wise, hence why Cos and Sin both = $\sqrt{2}$ /2 at 45 °

anyway

X = 1 / 2 * 12/ $\sqrt{2}$ /2

X = 3 $\sqrt{2}$

A=3

B= 2

:) nice , huh

Step-by-step explanation:

Hi there !

trucks/cars = 2/3 = x/9 = 30/y

x = 2×9/3 = 18/3 = 6

y = 3×30/2 = 90/2 = 45

Good luck !
