Subtraction property of equality is the answer.

Ok so where they went wrong was they subtracted incorrectly when trying to prove RSQ’s degree.


RSQ+35+75=180


So 35+75= 110
And when you subtract 180-110= 70°
BUT, in the box for subtraction property of equality, they write RSQ is equal to 75° which is incorrect because they subtracted wrong.

Can someone tell me the answer to this plz
Tpy6a [65]
M8 =43.
Reason:
134+ M8 =180(degrees). This is because angles on a straight line =180 (degrees)

180-134=M8
Therefore:
M<8 =180-134= 43 (degrees)

Hope this helps and makes sense.

13x-11 +18x15+ 4x+1=180°
BARSIC [14]

Answer:

x = - 80/17, or x = - 4 \frac{12}{17}

Step-by-step explanation:

13x-11 +18×15+ 4x+1=180°

<=> (13x + 4x) + (18×15+ 1 - 11)=180°

<=> 17x + 260 =180

<=> 17x = 180 - 260

<=> 17x = - 80

<=> x = - 80/17

<=> x = - 4 \frac{12}{17}
