If r=1/2
then r2 = 1
because 1/2 times 2 is 1
Complimentary angles add up 90°
let one of the angles be x, the 2nd angle will be (x+4)
thus the total sum will be:
x+(x+4)=90
2x+4=90
thus the right equation is:
<span>B. 2x + 4 = 90</span>
Answer:
0.64
Step-by-step explanation:
4 out of 5 free throws is 0.8 as a decimal.
The probability that Brian will make <em>2 free throws</em> is 0.8 for the first one, and then 0.8 of that for the second one. That means you multiply the two to get your answer and 0.8 times 0.8 = 0.64.
Step-by-step explanation:
As < A and < B are vertical angles so
<A = < B
5x + 12 = 6x - 11
6x - 5x = 12 + 11
x = 23
Hope it will help :)❤
