Answer:

The measure of angle x is 90°

Step-by-step explanation:

Given the figure in which

∠1=88°, ∠6=89°

we have to find the value of x.

∠5=∠6=89° (∵ Vertically opposite angles)

∠1+∠4=∠6 ( ∵ By exterior angle property)

88°+∠4=89°

∠4=89°-88°=1°

As AC=CB (both are radii of same circle)

∴ ∠4=∠3=1°

Now, by exterior angle property

x=∠5+∠3=89°+1°=90°

Hence, the measure of angle x is 90°

How to find all of the angles and sides of a triangle using sine

Hoochie [10]

Answer:

how to find them

Step-by-step explanation:

1. The sine of the angle = the length of the opposite side. the length of the hypotenuse.

2. The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

3. The tangent of the angle = the length of the opposite side. the length of the adjacent side.

The slope of the function for pronghorn antelope is 60.78 which infers that the rate of speed of the pronghorn is 60.78 miles per hour.

7) The given function that represents the speed of the pronghorn is

y = 60.78x - 5.4

Comparing this function with the general equation of a straight line

y = mx + c we can conclude that the slope of the function is 60.78 .

So the Pronghorn's rate of speed is 60.78 miles per hour.

8) Now the speed of the cheetah is given in the form of a table.

Let us take any two points on the graph

(0.5,21.85) and (2,118.60)

Slope of the line passing through these two points

= (118.6-21.85)/(2-0.5)

=64.5

So the slope of the graph is 64.5 and the average rate of speed of the Cheetah is 64.5 miles per hour.

9) From the above two slopes and the rate of speed we can conclude that the speed of the cheetah is 64.5 mph which is greater than that of the pronghorn 's speed of 60.78 miles per hour.

Liliana wants to write an equivalent expression for n + 3 minus 5 n + 6. Which of her attempts uses the algebraic properties cor

torisob [31]

Answer:

Option A.

Step-by-step explanation:

The given equation is

$n+3-5n+6$

Liliana wants to write an equivalent expression.

It can be written as

$n+(3-5n)+6$

Using commutative property, we get

$n-5n+3+6$ $[\because A+B=B+A]$

Using associative property, we get

$(n-5n)+(3+6)$ $[\because A+(B+C)=(A+B)+C]$

Using distributive property, we get

$(1-5)n+(3+6)$ $[\because An+Bn=(A+B)n]$

Using addition property, we get

$-4n+9$

Therefore, the correct option is A.
