3# Find the missing variable (s). Round to the nearest tenth.

rewona [7]

Answer:

Step-by-step explanation:

This triangle is already positioned to match trig functions (also known as circular functions).

Point A is origin, side AC (length x) is on X axis,

side CB (length y) is parallel to Y axis.

***** You just remember *****

cos is horizontal, on X axis,

sin is vertical, on Y axis.

To get from unit triangle with hypotenuse 1,

horizontal side cos(θ), vertical side sin(θ), you multiply all sides by same number, namely, the specified length of the hypotenuse.

***** that's all you need to know *****

Draw a unit circle centered at A, mark point Y at intersection of circle and AB, and drop a vertical line from Y crossing X axis at X.

Then radial segment AY is 1, AB is 10

horizontal segment AX is cos(32°), AC is 10AX

vertical segment XY is sin(32°), CB is 10XY.

So x = 10 cos(32°), y= 10 sin(32°).

Answer:

<h2>Function is y = x.</h2><h2>Domain: $-3 \leq x \leq 2$ .</h2><h2>Range: $-5 \leq y \leq 4$ .</h2>

Step-by-step explanation:

In the given image, the line passes through (-1, -1) and (1, 1).

Let the equation of the line is $y = mx + c$ , where m is the tangent of the line and c is a constant.

Putting the co-ordinates of the points in the equation, we get $-1 = -m + c$ and $1 = m + c$

From the two equations we get, c = 0 and m = 1.

Hence, the function is y = x.

Domain is $-3 \leq x \leq 2$ .

Range is $-5 \leq y \leq 4$

Step-by-step explanation:

Find the measure of the vertex angle ∠ABD of an isosceles triangle

we know that

An isosceles triangle has two equal sides and two equal angles

In this problem

∠ABD=∠BAD= ----> the angles of the base are equals

Find the measure of the vertex angle

∠ABD= ------> the sum of the internal angles of a triangle is equal to

Step 2

Find the measure of the angle ∠CBD in the equilateral triangle

we know that

A equilateral triangle has three equal sides and three equal angles

The measure of the internal angle in a equilateral triangle is

∠CBD=

Step 3

Find the measure of the angle ∠ABC

∠ABC=∠ABD+∠DBC

substitute the values

∠ABC=

therefore

the answer is

the measure of the angle ∠ABC is

X^2- 11 = 70 I need help on how to solve this

brilliants [131]

Answer: Add 11 to the other side of the equation, giving you 81. Then, since x is square you are going to need to square root both sides ( $\sqrt{x}$ this symbol). When you do that, you should get what x is! Let me know if you still need help!
