Answer:
R=50 degrees
Step-by-step explanation:
All of the angle measures together are 180 degrees. You need to make an equation in order to solve this problem:
180= (3x+5) + (11x-1) + (5x+5)
You then combine like terms:
180= (3x+11x+5x) + (5-1+5)
180= 19x+9
Then, subtract 9 from 180:
171= 19x
Then, divide 171 by 19:
9= x
Finally, you plug the value of x into the equation representing angle R:
5 x 9 + 5
45 + 5
50

Answer:
[tex]x=3,-7[/tex]
Step-by-step explanation:
We can solve for x by using [tex]\frac{-b\pm\sqrt{b^{2} -4ac} }{2a}[/tex]
By applying this on the quadratic equation, we get:
[tex]x=\frac{-4\pm\sqrt{4^{2}+84} }{2}[/tex]
Which simplifies to:
[tex]x=\frac{-4\pm10}{2}[/tex]
[tex]\therefore x=3,-7[/tex]

True or False? The blue radius is perpendicular to the green chord.
Answers
The statement that the blue radius is perpendicular to the green cord is false
From the complete question,
The blue radius does not bisect the green chord
This means that the blue radius and the green chord do not meet at 90 degrees
Since both lines do not meet at 90 degrees, then they are not perpendicular
Hence, the statement that the blue radius is perpendicular to the green cord is false

Holly stops to drink 5 ounces of water every two miles she
runs. The further that Holly runs, the more she drinks water.
Complete the table by writing two equivalent ratios
Answers
Answer:
the amount of water she drinks is x, the mileage is y:
x y
2 miles 5 oz
4 miles 10 oz
6 miles 15 oz
the ratios would be 4/10 and 6/15
Step-by-step explanation:
for every 2 miles Holly runs, she drinks 5 oz of water, right? the ratio is 5:2, so if you were to come up with other numbers that match the ratio, they have to be divisible by the parts of the ratio. so if she runs 2 miles, she drinks 5 oz. if she runs 4 miles, then she drinks 10 oz.
think of a ratio like a fraction (in this case it would be 2/5). if you were to make equivalent ratios, then the two fractions would have to be equal, right? well, when you simplify all of the numbers listed in the table above after making them into fractions, they would all go back to 2/5, so the numbers i came up with above are equivalent ratios, meaning they have the same value when simplified.
hopefully that helps and isn't too confusing! if you need other help, let me know! :)

c. Segment AC coincides with segment EF.
d. Segment BC coincides with segment ED.
e. Segment AB coincides with segment ED.
Answers
Answer: B.
C.
E.
Step-by-step explanation:
The true statements after the transformation, given that triangles ABC and EDF are congruent are: statements B, C, and E.
Recall what congruent triangles share in common:
If two triangles are congruent, all three sides of one triangle will be congruent to all corresponding three sides in the other triangle.If two triangles are congruent, all three angles of one triangle will be congruent to all corresponding three angles in the other triangle.Thus, if triangle ABC is congruent to triangle EDF, then Kiran will know that after the transformation:
<A will coincides with angle E<B will coincides with angle D<C will coincides with FSegment AC will coincides with EF, AB to ED, as well as BC to DF.
Therefore, the true statements after the transformation, given that triangles ABC and EDF are congruent are: statements B, C, and E.
