There are about 28 grams in an ounce so 45/28 is about 1.5
Yes, the triangle is right angled.
Step-by-step explanation:
Given lengths are;
11 yards, 60 yards and 61 yards
From pythagoras theorem;
The sum of square of shorter lengths is equal to square of larger side.
Here;
a = 11 , b = 60 , c = 61
As it satisfies the condition of Pythagoras theorem, the triangle is right angled.
Yes, the triangle is right angled.

Answer:
Step 2
Step-by-step explanation:
Because he didn't solve what was inside of the brackets, which would've been 20 divided by 4 if he did add the numbers inside of the brackets.
Answer:
34.44 miles
Step-by-step explanation:
Distance covered bty the two trains :
Distance = speed * time
Time = 30 minutes = 0.5hr
Distance of train 1 = 64 * 0.5 = 32 miles
Distance of train 2 = 52 * 0.5 = 26 miles
Included Angle = 72°
Using cosine rule :
a² = b² + c² - 2bcCosA
Let Distance between the trains after 30 minutes = a
a^2 = 32^2 + 26^2 - 2(32)(26) * Cos(72)
a^2 = 1700 - 514.20427
a^2 = 1185.7957
a = sqrt(1185.7957)
a = 34.435
a = 34.44 miles
