This theorem says that the exterior angle is equal to the sum of its remote interior angles. In other words, 140 = 2x + x + 2. 140 = 3x + 2 and 138 = 3x. Therefore, x = 46. Multiply it by 2 to get angle B is 92 degrees.
A: 100 because a perfect square is just a number squared and 10 squared is 100 :)
90% im pretty sure if I’m wrong don’t blame me
Answer:
0.52
Step-by-step explanation:
70% of the students chose to play on the play ground are boys.
60% of them are boys. So , logically 40% are girls.
40% of 60% is : * =
30% of the students stayed inside,
80% of them are girls .
80% of 30% is :
So 28%+ 24% = 52 %
There is a 0.52 probability that the student is a girl
Answer:
Step-by-step explanation:
312.50= a+0.25a
We need to combine like terms a=1. All variables without a value equal 1.
a+0.25a= 1.25a
312.50= 1.25a
Divide both sides by 1.25, since 1.25 is being multiplied by a.
a= 250
