Answer:
angle edf is 70
Step-by-step explanation:
triangle angles always add up to 180. So if you have 40 degrees at angle e already, 180-40 = 140
since side DE and side EF are congruent, that means its an isosceles triangle. One rule for that type a triangle is that the two base angles are equal. So you can just do 140/2 = 70
hope that helps!

Leslie and Surekha were standing on opposite sides of a road. Suddenly, they spotted a puppy stranded on the road and both rushed straight to where the puppy was, to pick it up. If Leslie ran at an angle of 35 degrees to the edge of the road and Surekha at an angle of 70 degrees, at what angle did their path meet?
Answers
Answer:
75°
Step-by-step explanation:
we can form a triangle to help us understand how to solve this problem:
puppy
∠ Leslie = 35° ∠ Surekha = 70°
If Leslie's angle is 35° and Surekha's angle is 70°, that gives us a total of 105°. Since the sum of the triangle's three angles is 180°, then the angle at which they will meet is 180° - 105° = 75°
In this exercise, we have to calculate the angle of the path that they met, so we will have:
75°
We know that the geometric figure in question is a triangle and that the sum of its internal angles must be equal to 180 degrees, thus:
[tex]180-105=X\\180-105=75\\[/tex]

Answer: equilateral
Step-by-step explanation:
Two sides of a triangle are equal in length, and the third slide is 5 less than the length of the equal sides. If the perimeter of the triangle is 49, how long are it's sides?
Answers
Answer:
The sides are 14.6, 14.6, 9.6
Step-by-step explanation:
Step one:
given
Perimeter= 49
let the equal sides of the triangle be x
so the third side will be x-5
hence the first side is=x
the second side =x
and the third side=x-5
the perimeter of triangle is
P= A+B+C
where A B and C represents all the sides
49=x+x+(x-5)
solve for x
49=2x+x-5
49=3x-5
49-5=3x
44=3x
x=44/3
x=14.6
Hence the third side is
=x-5=14.6-5
=9.6
The sides are 14.6, 14.6, 9.6

Your buddy constructs an angle bisector BD−→− for ∠ABC. She says that m∡ABD and m∡DBC formed by the angle bisector are congruent. Do you think that is always, sometimes or never true for angle bisectors?
Answers
Answer:
Always true
Step-by-step explanation:
The definition of an interior or internal angle bisector is the the dividing line segment that splits the angle into two equal angles (parts)
Therefore, given that the segment BD is the bisector of ∠ABC, then the formed angles m∡ABD and m∡DBC are, by definition of bisected ∠ABC, always congruent

- 2x² + x + 42x² + x + 43Step-by-step explanation:
Given functions
r(x) = x + 4s(x) = 2x²Finding (r-s)(x), (r+s)(x), (r*s)(-1)
(r - s)(x) = r(x) - s(x) = x + 4 - 2x² = - 2x² + x + 4(r + s)(x) = r(x) + s(x) = x + 4 + 2x² = 2x² + x + 4(r*s)(-1) = r(-1)*s(-1) = (-1 + 4)*(-1)² = 3*1 = 3Answer:
1. - 2x² + x + 4
2. 2x² + x + 4
3. Answer = 3
Example functions we are given:
r(x) = x + 4
s(x) = 2x²
Now, we Find (r-s)(x), (r+s)(x), (r*s)(-1)
(r - s)(x) = r(x) - s(x) = x + 4 - 2x² = - 2x² + x + 4
(r + s)(x) = r(x) + s(x) = x + 4 + 2x² = 2x² + x + 4
(r*s)(-1) = r(-1)*s(-1) = (-1 + 4)*(-1)² = 3*1 = 3
Please give me an explanation too I need help Solve for y: 2x-y=3
Answers
Answer:
y = 2x -3
Step-by-step explanation:
to solve for y, simply isolate the y so in this case move 2x to the right side of the equation in which it becomes -y= -2x +3 and then divide by -1 which is beside the -y essentially cause y cannot be negative so then the equation becomes y = 2x -3
Answer:
y=2x-3
Step-by-step explanation:
2x-y=3
-2x on both sides of the equal sign which leaves you with -y=-2x+3
divide both sides by negative 1
y=2x-3

Carlos bought 4 yards of packing tape. He used 1 3/5 yards on a package for his father and 2 1/3 for a package. How many yards of packing tape does Carlos have left (only write the fraction with no words as your answer)?
Answers
Answer:
1/15 yards
Step-by-step explanation:
Total yards of packing tape = 4 yards
Yards used for his father = 1 3/5 yards
Yards used for another package = 2 1/3 yards
Total yards used = 1 3/5 + 2 1/3
= 8/5 + 7/3
= 24+35/15
= 59/15 yards
How many yards of packing tape does Carlos have left
Total yards left = Total yards of packing tape - Total yards used
= 4 - 59/15
= 60-59/15
= 1/15
Total yards left = 1/15 yards

(SHOW YOUR WORK FOR A BRAINLIEST)
Answers
Answer:
C
Step-by-step explanation:
Answer:
B. 2,324 inches
Step-by-step explanation:
You need to find the circumference of the bike wheels first so that you know how much she would travel if her wheels rotated 1 time. Circumference of circle = pi × d
1 time = 20pi
37 times = 20pi × 37
= 740pi
= 2324.778564...inches
The diameter of a cartwheel is 2.1 m. Find the distance travelled when it completes 100 revolutions.
You need to find the circumference of the cartwheels first so that you know how much it would travel if her wheels revoluted 1 time. Circumference of circle = pi × d
1 revolution = 2.1pi
100 revolutions = 2.1pi × 100
= 210pi
= 659.7344573...m
The diameter of a circular park is 98 m. Find the cost of fencing it at $4 per meter.
You need to find the circumference of the park first so that you know how much it would cost. Circumference of circle = pi × d

Cost of fencing = 4 × 98pi
= 392pi
= $1231.50
≈ $1232.00
