PLEASE HELP ME SOLVE THIS, WHOEVER DOES WILL EARN 100 PTS!!!!!!!!!!!!!
Monica [59]

Step-by-step explanation:

(Assuming that this triangle is isosceles)

If this triangle is isosceles, then x° is going to be equal to its twin angle; 40°.

We can solve for z now.

180 = 40 + 40 + z

180 = 80 + z

Subtract 80 from both sides.

100 = z

z = 100°

Now that we know z = 100 degrees, we can begin to solve the expression (3x -20)

The expression sits on a 180° line and the angle z (100°) shares the line with the expression (3x - 20)°

180 = 100 + (3x - 20)

Subtract 100 from both sides.

80 = 3x - 20

Add 20 to both sides to isolate 3x

100 = 3x

Divide by 3 on both sides.

100/3 = 3x/3

33.33... = x

What is the square root of 49 multiplied by the square root of 9
fiasKO [112]
First we need to find the the answer to both the square root of 49 and 9.

The "square root" is a term referring to a number, multiplied by itself (x • x) would be = to your square root.

So for example: Square root of 16 = 4 because 4*4=16 

So lets get out numbers:

\sqrt{9} =3

\sqrt{49}=7

Now you multiply 3*7 (or 7*3) and you get 21.

Final answer: 21
