I NEED HELP ,PLAESE AYUDAAAAA POR FAVOR
Answer:
Step-by-step explanation:
First off, if side BC and side EC are congruent, then this is an isosceles triangle. It then goes to follow by the Isosceles Triangle Theorem that angle EBC is also 67 degrees. By the Triangle Angle-Sum Theorem then, angle BCE is 180 - 67 - 67 which is 46 degrees. Angle BCE is supplementary to angle FCA which means they add up to equal 180, so angle FCA is 180 - 46 = 134.
Angle FCA = 134

the ratio of North American butterflies to South American butterflies that a butterfly Park is 8:4 the ratio of South American butterflies the European butterflies is 4:2 there are 64 in North American butterflies in a butterfly Park part 1 out of 2 how many South American butterflies are there?
Answer:
5x - North American Butterflies.
3x - South American Butterflies.
5x = 30 (Divide By 5).
x = 6.
3x = 18.
3x - South American Butterflies.
2x - European Butterflies.
2x = 2 * 6 = 12
There Are 12 European Butterflies And 18 South American Butterflies.

Step-by-step explanation:
or,4x + 40 - 40 (subtract and the answer will be o ; no valueit will get )= 16-40
or, 4x = 16-40
therefore, 4x = 16-40

Step-by-step explanation:
In circle D, ∠EDH ≅ ∠EDG.
Circle D is shown. Line segment F H is a diameter. Line segments D E and D G are radii. Lines are drawn from point E to point G and from point E to point H to form secants. The length of E J is 4 and the length of E H is 9. The measure of arc F E is 57 degrees and the measure of arc F G is 66 degrees.
What is the length of JG?
4 units
5 units
6 units
9 units
Answer:
5 units
Step-by-step explanation:
The computation of the Length of DG is as follows;
Given that
∠EDH ≅ ∠EDG,
EH = 9,
EJ = 4.
Based on the above information, as we can see that the two sides i.e. corresponding are congruent
EH = EG (CPCTC)
EG = 9.........(i)
Now
EG = EJ + JG
EG = 4 + JG ........(ii)
Now after solving this
JG = 5 units
Hence, the second option is correct

if L is parallel to M, find the value of each variable(s)
Answer:
see below
Step-by-step explanation:
5. 9x + 2 = 119° alternate interior angles are congruent
9x = 117
x = 13°
6. 12x - 8 + 104° = 180° same side interior angles are supplementary
12x + 96 = 180
12x = 84
x = 7°
7. 5x + 7 = 8x - 71 alternate exterior angles are congruent
-3x = -78
x = 26°
8. 4x - 7 = 7x - 61 corresponding angles are congruent
-3x = -54
x = 18°
9. 9x + 25 = 13x - 19 corresponding angles are congruent
-4x = -44
x = 11°
13x - 19 + 17y + 5 = 180° straight line adds up to 180°
13(11) - 19 + 17y + 5 = 180
143 - 19 + 17y + 5 = 180
17y + 129 = 180
17y = 51
y = 3°
10. 6x - 7 + 3x - 29 = 180° same side interior angles are supplementary
9x - 36 = 180
9x = 216
x = 24°
6x - 7 = 8y + 17 vertical angles are congruent
6(24) - 7 = 8y + 17
144 - 7 = 8y + 17
137 = 8y + 17
120 = 8y
y = 15°
11. 49 + 3x = 7x - 23 corresponding angles are congruent
-4x = -72
x = 18°
3x = 11y - 1 corresponding angles are congruent
3(18) = 11y - 1
54 = 11y - 1
55 = 11y
y = 5°
12. 5x - 38 = 3x - 4 alternate interior angles are congruent
2x = 34
x = 17°
7y - 20 + 5x - 38 + 90 = 180° sum of triangle interior angle equals 180
7y - 20 + 5(17) - 38 + 90 = 180°
7y - 20 + 85 - 38 + 90 = 180°
7y + 117 = 180
7y = 63
y = 9°

Which rectangular equation represents the parametric equations x = 2sec(t) + 1 and y = 6tan(t)?
Answer:
A.)
Step-by-step explanation:
literally guessed but was right lol
Option first is correct.
What is rectangular equation?A rectangular equation, or an equation in rectangular form is an equation composed of variables like x and y which can be graphed on regular cartesian plane.
According to the given question
We have
x = 2sec(t) + 1 and y = 6tan(t)
Now the above expressions can be written as :
x -1 = 2sec(t)
⇒ [tex]sec(t)\frac{x-1}{2}[/tex]
similarly,
[tex]\frac{y}{6} = tan(t)[/tex]
From trigonometric identities we know that
[tex]1 + tan^{2} \ t = sec^{2} \ t[/tex]
Substitute the value of tant and sect in the above identity
[tex]1 + (\frac{y}{6} )^{2} =(\frac{x-1}{2}) ^{2}[/tex]
⇒[tex]\frac{(x-1)^{2} }{4} -\frac{y^{2} }{36} =1[/tex], this is the required rectangular equation.
Hence, option first is correct.
