Answer:
b = 7.56 cm
Step-by-step explanation:
Sum of the angles in a triangle = 180
so m∠A = 180 - 75 - 36 = 69 ;
use the law of sines:
(sin A) / a = (sin B) / b = (sin C) / C.
Now plug in ∠A = 69 into formula (sin A) / a = (sin B) / b and solve for b:
(sin 69) / 12 = (sin 36) / b
cross multiply:
b sin 69 = 12 sin 36 divide each side by sin 69
b = {12 sin 36} / sin 69
b = (12 sin 36) / sin 69 = 7.555........
b = 7.56
Answer:
B. 48
100-52 = 48
Step-by-step explanation:
When you are finding the range you are taking the lowest and highest numbers and finding the difference. So you would put the numbers in order from least to greatest then find the highest and lowest amounts.
What i dont see anything??
let "one number" = x, and "another" = y
x = 4y + 4
(x + y) - 4 = 28
Plug in 4y + 4 for x
4y + 4 + y - 4 = 28
Simplify. Combine like terms
5y = 28
Isolate the y. Divide 5 from both sides
y = 28/5
y = 5.6
Plug in 28/5 for y.
x = 4y + 4
x = 4(28/5) + 4
Simplify
x = 22.4 + 4
x = 26.4
x = 26.4, y = 5.6
hope this helps
No, it depends whether or not the two integers are positive or negative.
