Triangle Angle-Sum Theorem: The sum of the measures of interior angles is equal to 180°.
Then
m∠1+117°+33°=180°,
m∠1+150°=180°,
m∠1=180°-150°,
m∠1=30°.

Step-by-step explanation:
Answer:
t = 54.85714 seconds
Step-by-step explanation:
t = 12(210)+9000/210
t = (2520 + 9000) / 210
t = 11520 / 210
t = 54.85714 seconds
Answer:
62
Step-by-step explanation:
well, we start by expressing the number:
a b
we understand that using the above expression, the value of the number is 10a + b
using the information in the question,
a = 3b (1)
and,
11b + 11a = 88 (2) (derived using 10a + b form)
hence, when substituting (1) into (2):
11b + 33b = 88
44b = 88
b = 2 (3)
sub (3) into (1)
a = 6
hence, the number is 62
