A triangle has one side that measures x, and the other two sides each measure 4 inches less than x. The perimeter is 19 inches.

zalisa [80]

Perimeter of a triangle = all 3 sides added together

x + (x - 4) + (x - 4) = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 27/3
x = 9 <==

What is the value of h when the function is converted to vertex form?

elena-s [515]

Answer: h=7

Step-by-step explanation:

By definition the function in vertex form is:

$f(x)=a(x-h)^{2}+k$

Where (h,k) is the vertex of the parabola.

You must group the terms that contain the same variable in the function:

$f(x)=(x^{2}-14x)+29$

Complete the square as following:

$f(x)=(x^{2}-14x+49)+29-49$

Now you must rewrite it as following:

$f(x)=(x-7)^{2}-20$

Then:

h=7

if an exterior angle of a triangle has a measure of 35 degrees, what is the measure of the adjacent interior angle?

Alona [7]

Answer:

145

Step-by-step explanation:

Adjacent interior angle = x

Sum of exterior angle and adjacent interior angle = 180

35 + x = 180

x = 180 - 35

x = 145
