Answer:
Step-by-step explanation:
tan (60)=(sin 60)/cos 60=(√3/2)/(1/2)=√3≈1.732
The value of expression tan 60° is,
⇒ tan 60° = √3
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
To find the value of expression tan 60°
Now, We can find the value of expression as;
⇒ tan 60°
⇒ sin 60° / cos 60°
⇒ (√3 / 2) / (1 / 2)
⇒ √ 3
Thus, The value of expression tan 60° is,
⇒ tan 60° = √3

(Sat Prep) Find the value of x)
Answer:
1. x = 120°
2. x = 115°
Step-by-step explanation:
For the first question, you can see that the two lines are parallel. This means you can use any of the alternate interior angles, alternate exterior angles, corresponding angles, consecutive interior angles, and consecutive exterior angles.
You can see that the transversal cutting the two parallel lines make a 40° angle, and through alternate interior angles, the angle next to x is also 40°.
Because a straight line is 180°, the three angles that make up the straight line will add up to 180°. So:
x + 20° + 40° = 180°
x + 60° = 180°
x = 120°
For the second question, extend the line (the left one marked with 1 arrow) to make a smaller triangle attached to the parallelogram.
Because this is a parallelogram, opposite angles are congruent. So the opposite angle of x is also x.
Straight lines are 180°, so 180 - x will be what the angle measure is. If this is too confusing, refer to the image below.
Those two angles, 50° and (180 - x)°, will add up to be the exterior angle, which is also x.
So:
50 + 180 - x = x
230 = 2x
115 = x
x = 115
Solve for t.
-18.18 = 6t
Question 1 options:
t= -24.18
t= -3.03
t= 3.03
t= -13.18
Answer:
-3.03
Step-by-step explanation:
divide -18.18 by 6
Answer:
t= -3.03
Step-by-step explanation:
In order to solve for t, we need to isolate it. We would do this by dividing both sides by 6:
[tex]t= -18.18/6[/tex]
Therefore t= -3.03
Complete the equation.
(4x)−2(4x)3(4x)9=(4x)
Given:
Consider the given equation is
[tex](4x)^{-2}(4x)^3(4x)^9=(4x)^?[/tex]
To find:
The missing value in the given equation and complete the equation.
Solution:
We have,
[tex](4x)^{-2}(4x)^3(4x)^9=(4x)^?[/tex]
Taking LHS, we get
[tex]LHS=(4x)^{-2}(4x)^3(4x)^9[/tex]
[tex]LHS=(4x)^{-2+3+9}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
[tex]LHS=(4x)^{10}[/tex]
and,
[tex]RHS=(4x)^?[/tex]
Let the missing value be k.
For each equation LHS=RHS.
[tex](4x)^{10}=(4x)^{k}[/tex]
[tex]10=k[/tex]
Therefore, the missing value is 10 and the complete equation is [tex](4x)^{-2}(4x)^3(4x)^9=(4x)^{10}[/tex].

Here are the first four terms of a sequence.
5 9 13 17
Write an expression for the nth term of this sequence.
Answer:
4n + 1
Step-by-step explanation: The numbers are rising by 4, so this gives us 4n. Term number 1: 4n = 4, but the first number in the sequence is 5 so we have to add 1.
Term number 2: 4n = 8, but the second number in the sequence is 9 so, again, we have to add 1.

56 is 28% of an unknown number is (x)
Answer:
Change 28% to a decimal by moving the decimal point 2 places to the left:
28% = 0.28
Write the question as an equation to get:
56 = 0.28x
Now to solve for x, divide both sides by 0.28:
x = 56 / 0.28
x = 200
The unknown number is 200.
Step-by-step explanation:
Step-by-step explanation:
28% of an unknown number is (x)=56
28/100 of x=56
x=56×100/28=200i wanted to know the answer to this question so bad but i didnt let me ..so can somebody help me and i will give you the brainlist

PLEASE HELPP!! it’s due in an hour!!
Answer:
12x I think
Step-by-step explanation:
this is very confusing.
2x² + 2x - 4 = 2x ( x + 1 - 2 )
4x + 2x - 4
8x-4
4x = 2x ( x + 1 - 2)
8x + 2 - 2
8x + 4x
= 12x. I think 12x is the correct factor.
