Answer:
71°
Step-by-step explanation:
In order to be able to solve this problem, we must assume the relation between lines "a" and "b" is that they are parallel.
If a║b, then ∠1 and ∠2 are corresponding, hence congruent.
m∠1 = m∠2 = 71°
12/5 = 2.4 beats per second
2.4 * 30 = 72 beats

Answer:
29.7 for question 14
15a is 12.1
15b is 14
Step-by-step explanation:
In a 45 45 90 triangle, the legs are congruent, or the same length.
If we call the legs a, then the hypotenuse would be root 2 a.
So if the hypotenuse is 42, we divide by root 2 to get the length of each leg.
That should give us 29.7
In a 30, 60, 90 triangle, the short side is a, then the hypotenuse is 2a, and the longer side is a root 3.
So if the shorter side is 7, the longer side is 12.1, and the hypotenuse is 14.
Answer:
3/8
Step-by-step explanation:
This is simple probability and we have to divided the possible outcomes by total outcomes.
The sample space is given by 2 raises to power n where n is the number of tosses .
Here we have 5 tosses .
The Sample Space is 2⁵.
The possible arrangement of three tails would be 3!
The possible ways of arranging 2 Heads would be 2!
We want to find the probability of 3 tails and 2 heads
Therefore
P (3 tails and 2 heads ) = 3! 2!/ 2⁵
=2* 6/ 2⁵= 12/32= 6/16= 3/8
