Find the exact value of sin(140°)cos(20°) – cos(140°)sin(20°)
Given :
An expression sin(140°)cos(20°) – cos(140°)sin(20°) .
To Find :
The value of given expression .
Solution :
We know ,
sin(A - B) = sin A cos B - cos A sin B
By comparing with above formula , we get :
A = 140° and B = 20° .
So , sin(140°)cos(20°) – cos(140°)sin(20°) = sin ( 140°- 20°) = sin 120° .
Now , [tex]sin 120^\circ{} = \dfrac{\sqrt{3}}{2}[/tex]
Therefore , the value of expression is [tex]\dfrac{\sqrt{3}}{2}[/tex] .
Hence , this is the required solution .

In February 2009, the Harris Poll asked a sample of Americans whether they thought churches and religious groups have too much or too little power and influence on Washington†. The opinions of Americans were 34% too much, 57% too little, 4% just right, and 5% unsure.
Complete question is;
In February 2009, the Harris Poll asked a sample of Americans whether they thought churches and religious groups have too much or too little power and influence on Washington†. The opinions of Americans were 34% too much, 57% too little, 4% just right, and 5% unsure. (a) What type of distribution is this? cumulative frequency distribution simple frequency distribution cumulative percent distribution relative percent distribution (b) Knowing that 1,010 adults were polled nationwide, how many Americans polled felt that churches and religious groups have too little power and influence on Washington? (Round your answer to the nearest whole number.) Americans
Answer:
A) Relative percent distribution
B) 576 Americans
Step-by-step explanation:
A) We are given that the opinions of Americans were 34% too much, 57% too little, 4% just right, and 5% unsure.
This means that number of people in each of this category was divided by total number of people in the poll and multiplied by 100%.
Thus,it is relative percent distribution.
B) Since 1,010 adults were polled nationwide, therefore the number of Americans polled felt that churches and religious groups have too little power and influence on Washington = 57/100 × 1010 ≈ 576 people

fd - m = 8
Solve for d
Please help!
Answer:
[tex]d=\frac{8+m}{f}[/tex]
Step-by-step explanation:
[tex]fd-m=8[/tex]
Add m to both sides:
[tex]fd-m+m=8+m[/tex]
[tex]fd=8+m[/tex]
Divide both sides by f:
[tex]\frac{fd}{f}=\frac{8+m}{f}[/tex]
[tex]d=\frac{8+m}{f}[/tex]
Find KM in this segment .
Answer:
164
Step-by-step explanation:
7x + 24 = 6x - 20 + 64
7x - 6x = 64 - 20-24
x = 64 - 44
x = 20
KM = 7x + 24 = 7*20 + 24 = 140 + 24
KM = 164

In the adjoining figure, GP bisects angle BGH and HP bisects angle GHD. calculate the size of angle a.
Answer:
90°
Step-by-step explanation:
AB and CD are parallel lines and EF is reversal
Therefore angles BGH and DHG are consecutive interior angles
As we know the sum of consecutive interior angles equals to 180°:
∠BGH + ∠DHG = 180°Line GP bisects angle BGH , therefore
m∠PGH = 1/2*m∠BGHLine HP bisects angle GHD, therefore
m∠PHG = 1/2*m∠GHDSum of two angles of triangle GHP:
m∠PGH + m∠GHD = 1/2(∠BGH + ∠DHG) = 1/2*180° = 90°Therefore the missing angle a is:
∠a = 180° - (m∠PGH + m∠GHD) = 180° - 90° = 90°PLEASE HELP ME THIS IS DUE IN 90 MINUTESSS

Answer:
x = 25
Step-by-step explanation:
2x + 4 + x + 11 = 90, combine like terms
3x + 15 = 90, subtract 15 from both sides
3x = 75, divide by 3
x = 25, you have your answer!

Explanation:
The tickmarks indicate which segments are the same length. On the left side, the single tickmark segments are the same length, and the same can be said about the double tickmarks segments as well. Because of this, the segment x cuts the diagonal sides in half.
The segment x is known as a midsegment of the triangle. It is half as long as the parallel side of 24 units. So x = (1/2)*24 = 12.

Which property will help solve One-ninth + t = 7 for t?
addition property of equality
transitive property of equality
symmetric property of equality
multiplication property of equality
Answer:
addition property of equalityStep-by-step explanation:
Adding the same number to both sides of equation doesn't change the equality.
¹/₉ + t = 7
+(-¹/₉) +(-¹/₉)
t = 7 + (-¹/₉) = 7 - ¹/₉ = 6⁸/₉
addition property of equality

Name a pair of complementary angles (there may be more than one pair).
<1 and <5
<1 and 2
<2 and <4
<3 and <4
<5 and <4
Answer:
∠3 and ∠4
Step-by-step explanation:
In this diagram, angles 3 and 4 are the only pair whose sum is 90°.
In this given figure, [tex]\angle{3}[/tex] and [tex]\angle{4}[/tex] are the only pairs of angles that have the measure of 90°.
So,[tex]\angle{3}[/tex] & [tex]\angle{4}[/tex] are the pair of angles.

What is the 50th term of Arithmetic sequence 9,2,-5
Answer:
- 334
Step-by-step explanation:
There is a common difference between consecutive terms in the given sequence, that is
d = 2 - 9 = - 5 - 2 = - 7
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 9 and d = - 7 , thus
[tex]a_{50}[/tex] = 9 + (49 × - 7) = 9 - 343 = - 334
