Answer:
c)the diagonals bisect eachother
Answer:
Step-by-step explanation:
10 - m = m - 10 is one solution
7x + 5 = 7(x + 5) is no solution
3(t + 2) = (2 + 3t) + 4 is identity
hope this helps!
mark me brainliest :D
Answer:
136 Degrees
Step-by-step explanation
Set up as (3x+11) + (5x-9) = 90
then solve for x using algebra.
you can do this because angle NSO and RSQ are eqaul once you know x you will be able to solve all the other angles and subtract from 360 (the total angle) to find NSR.
Steps:
3x+11+5x-9 = 90
8x+2=90
<u>x= 11</u>
Solve 3(11)+11 = 44
add known angles:
44+90+90 = 224
360-224 = 136 degrees
We use concepts like <u>complimentary angles</u> and<u> vertical angle theroem</u>.
The second one
Hope this helps :D
Subtract 3 on both sides.
Add x....

Multiply by 3
Divide by 4
