Find the value of x need help

Mathematics
1 answer:
amm18122 years ago
5 0

Answer:

x=-10

Step-by-step explanation:

since there's a given 120 degrees, and it's a isosceles triangle, we know that the line adds up to 180 (where the 120 degrees is). so 120+x=180, the interior angle measures 60 degrees. That being said, the 3 angles measure 60 degrees also. now there's a right angle mark on top, so we find the angle of the smaller triangle (near angle 2) by doing 90-60=30 degrees.

angle 2 is said to be x+160, and there's a line, which tells us that they must add to 180.. so x+160+30=180

x+190=180

x=-10.

Х<br> 2+4 = 2(x - 1)?<br><br> Can someone help me out
ELEN [110]

Answer:

x=4/3

Step-by-step explanation:

2+4=2(x-1)    original

6=2(x-1)        combine like terms

6=2x-2         multiply x-1 by 2

8=2x            add 2 to both sides

4=x              divide both sides by 2

Is it possible to draw a triangle with numbers 5,6,11
Tatiana [17]

Answer:

No

Step-by-step explanation:

Let's use the Pythagorean Theorem. For those of you that don't know, it is a^2 + b^2 = c^2\\.  

11 is the bigger side in this case, so our formula would go like this: 5^2 + 6^2 = 11^2\\.

We now calculate to see if this is true.

25 + 36 \neq 121

Therefore, the answer is wrong.
