If m∠BAC=(7x+1)° and m∠BCA=(5x+9)°, what is the measure of the vertex angle? Show your work to support your answer.
expeople1 [14]

Answer:

128degrees

Step-by-step explanation:

Note that the given triangle ABC is an isosceles triangle with base angles equal, hence;

m∠BAC = m∠BCA

7x+1 = 5x+9

7x - 5x = 9-1

2x = 8

x = 8/2

x = 4

m∠BAC = 5x+6

m∠BAC = 5(4)+6

m∠BAC = 26 degrees

The vertex angle = 180 - (26+26)

The vertex angle = 180 - 52

The vertex angle = 128degrees

Examine the relation.
iragen [17]

Answer:

not a function I don't know the range tho

Step-by-step explanation:

Since  x = 3  produces  y = 3 and  y = − 2 , the relation  ( − 2 , − 2 ) , ( − 2 , 4 ) , ( -1 , 1 ) , ( 1 , 0 ) , ( 1 , 1 ) , ( 3 , 3 ) , ( 3 , − 2 ) is not a function.

Which is a zero of the quadratic function f(x) = 16x2 32x â’ 9? x = â€""5. 25 x = â€""2. 25 x = â€""1. 25 x = â€""0. 25.
Fynjy0 [20]

The zeros of the quadratic expression are 1/4 and -9/5

Given the quadratic function:

  • 16x^2 + 32x - 9

To get the zeros of the function, we will equate the function to zero to have:

  • 16x^2 + 32x - 9  = 0

Factorize the function;

16x^2 + 36x - 4x - 9 = 0

4x (4x+9) - 1(4x + 9) = 0

(4x - 1) (4x + 9) = 0

4x - 1 = 0 and 4x + 9 = 0

4x = 1 and 4x = -9

x = 1/4 and -9/5

Hence the zeros of the quadratic expression are 1/4 and -9/5
