Mathematics

Answer:

Step-by-step explanation:

triangle ABC is an equilateral so all angles and sides are equal to each other

AB = 6

triangle DEF is an isosceles so two of its angles are equal to each other

a triangles angles add up to 180°

to find the measure of these angles we’ll write this equation:

x + x + 40 = 180

and solve for x

2x + 40 = 180

2x = 140

x = 70°

so mF is 70°

If y varies directly as x and y = 24 when<br> x= 16, what is y when x = 50?

mars1129 [50]

Answer:

$y = 75$

Step-by-step explanation:

Given

$y\ \alpha\ \ x$

$y=24; x =16$

Required

Find y when $x = 50$

We have:

$y\ \alpha\ \ x$

Express as equation

$y = kx$

Solve for k

$k = \frac{y}{x}$

When $y=24; x =16$

$k = \frac{24}{16}$

$k = \frac{3}{2}$

When $x = 50$ , we have:

$y = kx$

$y = \frac{3}{2} * 50$

$y = 75$

The combined area of the 3 windowpanes and frame shown below is 924 in.2. The frame is of uniform width. What is the side length

wariber [46]

Answer:

Option A. $x=10\ in$

Step-by-step explanation:

we know that

The combined area of the 3 windowpanes and frame is equal to

$(3x+12)(x+12)=924\\ \\3x^{2}+36x+ 12x+144=924\\ \\ 3x^{2}+48x-780=0$

using a graphing tool to solve the quadratic equation

The solution is $x=10\ in$

see the attached figure
