Answer:

x = 30

y = 2

Step-by-step explanation:

Please note: the value for x is correct only if this triangle is a right triangle.

This can be solved because 2(5y) = 20 and because if a triangle has all congruent angles then its side lengths are also congruent.

Answer:

I believe the answer will be 63 degrees not 100% sure tho

Step-by-step explanation:

The reason is because triangle FHE measures 27 degrees it looks like FHE is a right triangle so there needs to be a total of 90 degrees in a right triangle so 90-27=63 like I said not 100% correct

Mindy is driving 32mi / h as she nears an elementary school. A first grade student runs into the street after a soccer ball, and

kifflom [539]

Answer:

11 meters is her approximate reaction distance.

Step-by-step explanation:

Speed of the car of Mindy = 32 mile/hour = $\frac{32\times 1609.34 m}{3600 s}$

1 mile = 1609.34 m

1 hour = 3600 seconds

Duration for her reaction last after student runs into street in front of her = $\frac{3}{4} seconds$

Distance covered three -quarters of a second = d

$d=\frac{32\times 1609.34 m}{3600 s}\times \frac{3}{4} s$

d = 10.73 m ≈ 11 m

11 meters is her approximate reaction distance.

I also need help with this one ?

uranmaximum [27]

Step-by-step explanation:

Line is intersecting x - axis at (-4, 0) & y - axis at (0, 2)

$\frac{x-x_1 }{x_1 - x_2 } = \frac{y-y_1 }{y_1 - y_2 } \\ \\ \therefore \: \frac{x-( - 4) }{ - 4 - 0 } = \frac{y-0 }{0 - 2 } \\ \\ \therefore \: \frac{x + 4 }{ - 4 } = \frac{y}{ - 2 } \\ \\ \therefore \: \frac{x + 4 }{ 2 } = \frac{y}{ 1 } \\ \\ \therefore \:y = \frac{x + 4 }{ 2 } \\ \\ \huge \pink{ \boxed{\therefore \:y = \frac{x}{ 2 } + 2}} \\$

Is the required equation of line.
