Answer:

x = 24, y = 131

Step-by-step explanation:

The sum of the 3 angles in Δ ABC = 180°

Sum the 3 angles and equate to 180

72 + 35 + 25 + 2x = 180 , that is

2x + 132 = 180 ( subtract 132 from both sides )

2x = 48 ( divide both sides by 2 )

x = 48

--------------------------------------------

Similarly in the lower triangle

25 + x + y = 180

25 + 24 + y = 180

49 + y = 180 ( subtract 49 from both sides )

y = 131

olga2289 [7]

the equation of the line is y = 3.

the slope of the line is 0.

the y-intercept is 3, so plug it into the slop-intercept-form equation:

y = mx + b

y = 0x + 3

y = 3

If f(x)= x^2-2x+4, find f(-2)

bekas [8.4K]

F(x) = x^2 -2x + 4

f(-2) = (-2)^2 -2(-2) +4
f(-2) = 4 + 4 + 4
f(-2) = 12
12 is your answer

Hope this helps

You are building a shed with your mother. A piece of wood is 4 feet long. How many 2/3 sections can you cut out of each piece of

lilavasa [31]

Answer: We can cut <u>6</u> $\dfrac23$ sections out of each piece of wood.

Step-by-step explanation:

Given: A piece of wood is 4 feet long.

Number of $\dfrac23$ sections = $4\div\dfrac23$

$=4\times\dfrac{3}{2}\ \ \ \ [\because \dfrac{a}{b}\div\dfrac{c}{d}=\dfrac{a}{b}\times\dfrac{d}{c}]\\\\=2\times3\\\\=6$

i.e. Number of $\dfrac23$ sections = 6

Hence, we can cut <u>6</u> $\dfrac23$ sections out of each piece of wood.
