Trigonometry, IF Answer Is Delivered On Time WILL Give BRANLIEST

Answer 1

Answer:

x=37°

y=6

Step-by-step explanation:

(ASSUMING BD is a perpendicular bisector of AC, otherwise answers maybe be wrong)

Consider the triangle ABC:

AB is the same length as BC (marked), meaning ABC is an isosceles triangle.

Since ABC is isosceles, ∠BAC=∠BCA=53

All angles in a triangle add up to 180:

180=∠ABC + ∠BAC + ∠BCA

180= ∠ABC + 53 +53

∠ABC = 180 - 106

∠ABC = 74

Assuming BD bisects ∠ABC perfectly, x is half of ∠ABC.

x=74/2=37

If BD bisects AC perfectly, AD=DC=y=6

The Royals softball team won 55 games and lost 25 games. What percent of the games did they lose? Round to the nearest whole percent.
_______% games lost

Answers

Answer:

31% games lost.

Step-by-step explanation:

Given that the Royals softball team won 55 games and lost 25 games, the following calculation must be performed to determine the percentage of games they lost out of the total games played:

55 + 25 = 80

80 = 100

25 = X

(25 x 100) / 80 = X

2,500 / 80 = X

31.25 = X

Thus, rounded to the nearest percentage, the Royals lost 31 percent of their games.

Answer:

[tex] r = 6\sqrt{3} [/tex]

Step-by-step explanation:

Area of the shaded section = θ/360*πr²

Area = 15π m²

θ = 360° - 310° = 50°

r = ??

If in the values into the equation and solve for r

15π = 50/360 × π × r²

[tex] 15 \pi = \frac{5 * \pi * r^2}{36} [/tex]

Multiply both sides by 36

[tex] 15 \pi * 36 = \frac{5\pi * r^2}{36}*36 [/tex]

[tex] 540 \pi = 5\pi * r^2[/tex]

Divide both sides by 5π

We are given that all three angles of ∆DEF is congruent to all the three corresponding angles of ∆XYZ. However, this is is not enough to prove that they are both congruent to each other. There's no information about any of tge side length.

AAA is not a criterion that proves two triangles are congruent.

Find the value of c so that (x+3) is a factor of the polynomial p(x). p(x)=x^3-4x^2+cx+33

Answers

Answer:

The value of c is -10.

Step-by-step explanation:

Since (x+3) is a factor of the polynomial p(x).

We have that:

x + 3 = 0 -> x = -3

So p(-3) = 0

Then

[tex]p(x) = x^3 - 4x^2 + cx + 33[/tex]

[tex](-3)^3 - 4(-3)^2 - 3c + 33 = 0[/tex]

[tex]-27 - 36 - 3c + 33 = 0[/tex]

[tex]3c = -30[/tex]

[tex]c = -\frac{30}{3}[/tex]

[tex]c = -10[/tex]

The value of c is -10.
