A triangle has one angle that measures 56∘ and one angle that measures 63∘. The measure of the triangle's third angle is _____ d

ElenaW [278]

Answer:

61 degrees

Step-by-step explanation:

Let's do this

So we know all the angles measure in a triangle will be 180 degrees

We have 56 and 63

To find the third, let's add and subtract

56+63=119

Now let's subtract from 180

So 180-119=61

The third angle measures 61 degrees

Now let's add them up and see if they total 180 degrees

So 56+63+61=180

Yay, we found the answer!

The answer is 61 degrees.

Which expression is equivalent to -1/2(-3/2x+6x+1)-3

stira [4]

Answer:

$-\frac{9}{4}x-\frac{7}{2}$

Step-by-step explanation:

We want to find an expression that is equivalent to $-\frac{1}{2}(-\frac{3}{2}x+6x+1)-3$ .

Since we can;t get the options, we simplify the given expression.

The reason is that, the given expression will be equivalent to the simplified one.

We combine similar terms to get:

$-\frac{1}{2}(\frac{9}{2}x+1)-3$

We now expand to get:

$-\frac{1}{2}*\frac{9}{2}x-\frac{1}{2}-3$

We perform the subtraction of the last two terms to get:

$-\frac{1}{2}*\frac{9}{2}x-\frac{7}{2}$

We now multiply to get:

$-\frac{9}{4}x-\frac{7}{2}$
