Hi there!

The included angle of sides JG and GH is angle G (JGH). This is because that is the angle the two line segments create.
Angle H is the opposite angle to side JG. If you draw a line from the angle straight down and extended the base, you'd see that the line intersected that side and that side only.
The side opposite to angle J is side GH. As I explained above, drawing a line would show you the intersection.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Identify the factors of x2 + 16y2.

BabaBlast [244]

The way to find the factores is by seeking the polonomial's roots, or zeros!

To find the roots, we set the polinomial equation to zero:

x^2+16y^2=0

Then we solve this equation:

x^2=-16y^2

This is only true, if x=y=0.

Answer:

C) 405.3 ft

Step-by-step explanation:

A triangle is a polygon with three angles and three sides. Types of triangle are scalene, isosceles, equilateral, right angled triangle.

Given a triangle with angles A, B, C and the corresponding sides directly opposite to the angles as a, b, c. The sine rule states that:

$\frac{a}{sin(A)}= \frac{b}{sin(B)} =\frac{c}{sin(C)}$

In the triangle formed by point C, ship B and ship A, we have ∠A = 82°, ∠B = 78°, c = AB = 140 ft. Hence:

∠A + ∠B + ∠C = 180° (sum of angles in a triangle)

82 + 78 + ∠C = 180

∠C + 160 = 180

∠C = 20°

Using sine rule:

$\frac{c}{sin(C)}=\frac{a}{sin(A)}\\\\\frac{140}{sin(20)}=\frac{a}{sin(82)}\\\\a= \frac{140*sin (82)}{sin(20)}\\\\a=405.3\ ft$

a = distance from Ship B to the signal fire at point C

What is the scale factor from AABC to ADEF?

8_murik_8 [283]

Answer: 8

Step-by-step explanation:

We are going from a smaller triangle to a larger triangle, so the scale factor is greater than 1.

Eliminate A and D.

We know scale factor = (image)/(preimage), so the scale factor is 32/4 = 8
