Answer:
Angle A is 40 Degrees
Angle B is 60 Degrees
Step-by-step explanation:
Angle C = 80 Degrees.
Angle A = 1/2 x Angle C ( 1/2 *80)
Angle B = 3/4 x Angle C (3/4 * 80)
Angle A:
80 * 0.5 = 40 (half of 80 since 1/2) = 40 Degrees
Angle B:
80 * 0.75 = 60 (three fourths of 80 since 3/4) = 60 Degrees
Check:
All angles of a triangle equal to 180 Degrees for any Triangle.
Therefore;
Angle A + Angle B + Angle C = 180 Degrees
40 Degrees + 60 Degrees + 80 Degrees = 180 Degrees
180 Degrees = 180 Degrees
So it checks out, so voila! :)
Hi Marisa255,
Solution:
First lets solve the given equation:
= 24 / 6 + 20
= 4 + 20
= 24
Now Lets solve A:
= 3(7 + 1)
= (3 x 7) + (3 x 1)
= 21 + 3
= 24
So we see that A and the equation given have the same answers.
Final Answer:
A. 3(7 + 1)
There are 1760 yards in a mile. 1760 x 3 = 5280
Hope this helped!
Answer:
i don't knpw good luck though
Step-by-step explanation:
Answer:
0.6 = 60% probability that it is either sunny or rainy.
Step-by-step explanation:
We solve this question treating these events as Venn probabilities.
I am going to say that:
Event A: Rain
Event B: Sun
The chance of rain is 20%
This means that 
The chance of it being sunny is 60%
This means that 
The chance of it being sunny and rainy at the same time is 10%.
This means that 
Calculate, the probability that it is either sunny or rainy.
This is:

0.6 = 60% probability that it is either sunny or rainy.
