Answer:

x = 69 v = 103

Step-by-step explanation:

Angles in a triangle add up to 180 degrees:

34 + 77 + x = 180

x = 69

Angles on a straight line add up to 180:

77 + v = 180

v = 103

Answer:

<h2><u><em>x = 69°</em></u></h2><h2><u><em>V = 103°</em></u></h2>

Step-by-step explanation:

the sum of the interior angles in a triangles is 180°, take away from 180 the know angles (34° and 77°) and you will have your answer

180 - 34 - 77 = 69°

Now we find angle V

The angle V and the angle of 77 ° are on a straight line, so the sum is 180°, from 180° you subtract 77 ° and you have the value of V

180 - 77 = 103 °

Let P(x) = 3x³-ax+b. If P(1) = P(-1) and P(2)=16, find the values of a and b
kozerog [31]

P(1) = P(-1)

P(1) = 3 - a + b
P(-1) = -3 + a + b

-> 3 - a + b = -3 + a + b
-> 3 - a + b + 3 - a - b = 0
-> 6 - 2a = 0
-> a = 3.

P(2) = 24 - 2a + b -> 24 - (2a - b) = 16 -> 2a - b = 8
-> 6 - b = 8
b = -2.

So, a = 3 and b = -2

Recheck : P(1) = 3 - 3 + (-2) = -2
P(-1) = -3 + 3 + (-2) = -2 => P(1) = P(-1) (true)

P(2) = 24 - 6 + (-2) = 16.

HELP SUPER FAST PLS
givi [52]

Answer:

GCF = 5

Step-by-step explanation:

15x² - 10x + 5

x is not contained in all 3 terms thus is not a factor

15 has factors 1, 3, 5, 15

- 10 has factors ± 1, ± 2, ± 5 , ± 10

5 has factors 1, 5

The common factors are 1, 5

Then GCF = 5

Jayden and Sheridan both tried to find the missing side of the right triangle. Jayden's Work Sheridan's Work a2 + b2 = c2 a2 + b
Svetlanka [38]

No, they are both incorrect by my understanding of your question use the Pythagorean theorem a^2 + b^2 =c^, therefore, 7^2 +x^2 = 13^2 or 49+x=169 then solve normally 169-49=120  √120 =5

The answer is 5
