Answer:
∠ E = 57°
Step-by-step explanation:
Since DF = EF then the triangle is isosceles with 2 base angles congruent , so
∠ E = ∠ D = 4x + 1
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
4x + 1 + 4x + 1 + 5x - 4 = 180 , collect like terms
13x - 2 = 180 ( add 2 to both sides )
13x = 182 ( divide both sides by 13 )
x = 14
Then
∠ E = 4x + 1 = 4(14) + 1 = 56 + 1 = 57°

Tn2= 6
Tn3=-12
Tn4= 24
Tn5= -48
Step-by-step explanation:
Tn= ar^n-1
Now
Tn1= -3×-2^1-1
=-3×-2^0
= -3×1= -3
Tn2= -3×-2^2-1
= -3×-2=6
Tn3= -3×-2^3-1
= -3×-2^2
=-3×4= -12
Tn4= -3×-2^4-1
= -3×-2^3
= -3×-8= 24
Tn5= -3×-2^5-1
= -3×-2^4

Answer:
< b = 73°
Step-by-step explanation:
The angle with a measure of < 73° has the same measure as < b because they are vertical angles. Two angles are vertical angles if they are opposite angles formed by the intersection of two lines. Vertical angles are congruent.
Therefore, the correct answer is: < b = 73°

Jesus bought 3 pairs of jeans for $71.40. How much would he need to pay for 8 pairs of jeans?
Answers
Answer:
$190.4
Step-by-step explanation:
I divided the 71.40 dollars by three to find how much one pair would cost and then multiplied that by 8 to find how much 8 pairs would cost.
first you find out how much every pairs of pants cost, (23.80) times that by 3 you get 71.40 so 23.80 times 8 = 190.4

- 6x < 24
solve for x and what’s the solution?
Answers
Answer:
x > -4
Step-by-step explanation:
In order to get x by itself, you divide -6 on both sides. So, -6x divided by -6 = x and 24 divided by -6 equals -4.
However, the answer is not x < -4 because a rule of inequalities states that any time you divide or multiply both sides of an inequality by a negative number, the inequality sign is flipped. So, the answer is x > -4
Answer:
x > -4
Step-by-step explanation:
- 6x < 24
Divide each side by -6, remembering to flip the inequality
-6x/-6 > 24/-6
x > -4

The diameter of a circle is 2 centimeters. What is the area?
d=2 cm
Answers
Answer: 4π cm or 12.56 cm
Step-by-step explanation: To find the circumference of this circle, start with the formula for the circumference of a circle which is C = 2πr.
Since the radius is 2 centimeters, we can
plug in 2 centimeters for r in the formula.
So we have (2)(π)(2 cm) which is equal to 4π cm.
So the circumference of this circle is 4π cm.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.
So we have (4)(3.14) which is equal to 12.56.
So the circumference of the circle is
approximately equal to 12.56 cm.
