I think the answer should be 24
Use sine, cosine or tangent of your calculator.
e.g. Q.7
Answer:
From the Pythagorean theorem...
[ distance between (a, 7) and (2, 1) ]2 = [a - 2]2 + [7 - 1]2
And they tell us that the distance equals 3√5 , so
[ 3√5 ]2 = [a - 2]2 + [7 - 1]2
45 = [a - 2]2 + 36
9 = [a - 2]2
±√9 = a - 2
± 3 = a - 2
± 3 + 2 = a
a = 3 + 2 = 5 or a = -3 + 2 = -1
and
5 + -1 = 4
Step-by-step explanation:
hope dis helps
1= 4/4 therefore 2=8/4
8/4 + 1/4 = 9/4
So Steve bought 9/4 of pizza total
