Answer:

x = 55

y = 55

z = 70

Step-by-step explanation:

x + 125 is a straight line, 180⁰ x+125=180 x=55⁰

since this is an <u>isosceles</u><u> </u><u>triangle</u><u>,</u><u> </u><u>x</u><u> </u><u>=</u><u> </u><u>z</u>

<u>and</u><u> </u><u>the</u><u> </u><u>sum</u><u> </u><u>of</u><u> </u><u>all</u><u> </u><u>angles</u><u> </u><u>in</u><u> </u><u>any</u><u> </u><u>triangle</u><u> </u><u>is</u><u> </u><u>1</u><u>8</u><u>0</u><u>⁰</u><u> </u>

<u>5</u><u>5</u><u>+</u><u>5</u><u>5</u><u>+</u><u>y</u><u>=</u><u>1</u><u>8</u><u>0</u><u>⁰</u>

<u>y</u><u> </u><u>=</u><u> </u><u>7</u><u>0</u><u>⁰</u>

Answer:

x=55º, y=70º, z=55º

Step-by-step explanation:

We have that xº = 180º - 125º = 55º

As it is an isosceles triangle, we have xº = zº = 55º

Therefore, yº = 180º - (xº + zº) = 180º - (55º + 55º) = 180º - 110º = 70º

0.6 + 15b + 4 = 25.6 all equivelant
Mila [183]

Answer:

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

Step-by-step explanation:

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

0.6 + 15b + 4 = 25.6 all equivelant

Hey there! 

Assuming that "f" =  y

So, let's solve your function,  shall we? 

y(-1) = 2 \\ \\ \\ -y= 2 \\ \\ DivideBy(-1)  \\ \\ \\   \frac{-y}{1}  =  \frac{2}{-1} \\ \\ \\ CancelOut:  \frac{-y}{1}  \\ \\ \\ Keep:  \frac{2}{-1}  \\ \\ \\ \\ Answer: y = -2 (option D)

Good luck on your assignment and enjoy your day!

The sum of 3 consecutive integers is 78. What is the integer closest to zero?
vova2212 [387]

Answer:

25

Step-by-step explanation:

Let n be the first integer.

Then the second integer will be (n + 1).

And the third will be (n + 2).

The sum is 78. Therefore:

n+(n+1)+(n+2)+78

Solve for n. Combine like terms:

3n+3=78

So:

3n=75

Therefore:

n=25

Therefore, the first integer is 25.

So our sequene is 25, 26, and 27.

The integer closest to zero will thus be 25.
