qwelly [4]

-3y^{9}

This value above is ONE term. Even though it is made up of more values and stuff, it is all one term BECAUSE they are all connect, so the -3 is with the y by multiplication, and the 9 is with -3y as an exponent of y.

Find x<br> 27 degrees and 32 degrees will give brainlist
telo118 [61]

Answer:

x = 121°

Step-by-step explanation:

If you add up all the angles of a triangle, you get 180°.

So you must add up all the angles.

27+32+x=180\\\\59+x=180

Next you subtract 59 on both sides.

x=121

x should be 121°.

If you would like to check your answer, you can add up 27, 32, and 121. If it all equals to 180, then your answer is correct.
