It should be for seconds...
30min(60sec/min)=1800s
(688-684) x 222
You have to do what’s in the parentheses first because of PEMDAS
688-684=4
Then you have to multiply
4x222
=888
Answer:
x=4
Step-by-step explanation:
16-4=12
3x=12
3*4=12
Use linear pairs to find the measure of angle B and the measure of the angle adjacent to the measured angle 135. Use the vertical angle theorem to find that angle inside the triangle across from B. Then use the triangle angle sum theorem to add up your values to equal 180. Solve for x and then plug that value back into 31 +x.
