Answer:
Step-by-step explanation:
d = c-b / a-n
Make b the subject
d (a - n) = c - b
-b = d (a - n) / c
Divide both sides by - 1
-b / -1 = d (a - n) / c ÷ -1
b = d (a - n) / c × 1/-1
= d(a - n) / - c
= ad - an / - c

Answer:
See below in bold.
Its the second choice.
Step-by-step explanation:
The sides b and d are the legs of a 30-60-90 triangle so the sides are in the ratio 2 : 1 :√3 where 2 = the hypotenuse.
Here the hypotenuse = 10. Therefore:
10 = 2*5, so d = 1/2 * 10 and b = √3*5.
d = 5 , b = 5√3.
Now a , b and c are also the sides of a 30-60-90 triangle and we know that b = 5√3.
So a ( the hypotenuse = 2 * 5√3 = 10√3.
and c ( the longest leg) = 5√3 * √3 = 15.
D. 53.659 seconds
explanation: 27.98+25.679 = 53.659
Y=2x-4
The slope is 2 and the y intercept is -4
Answer:
No, a triangle cannot have 2 obtuse angles. The definition of an obtuse angle is an angle with a measure that is greater than 90°.
