I think you forgot to give the diagram of the triangle along with the question. I am answering the question based on my knowledge and research. "cos B = sin (90^o - B)" is the one property among the following choices given in the question that <span>can be justified using the ratios in triangle CAB. The correct option among all the options that are given in the question is option "C".</span>
Step-by-step explanation:
we first square both sides to eliminate the square root brackets..
(√(m(y+n)/y)²= p²
m(y+n)/y = p²
(my +mn)/y =p²
so we multiply both sides by y to eliminate the denominator,
(my+mn)/y*y =p²*y
my+mn = p²y
collecting like terms,we have:
mn= p²y-my
so we seperate the y on the right hand side from the rest to have
mn = y(p²-m)
so divided both sides by the value in the bracket on the right hand side we have..
mn/(p²-m)=y(p²-m)/(p²-m)
so we have,
y= mn/(p²-m)
Answer:
x= 7 1/2
Step-by-step explanation:
Subtract the 1/2 to get it out of the way (whatever you do on one side of the = sign you have to do to the other)
So 10- 1/2= 9 1/2
Subtract the 2 to get it out of the way
9 1/2-2=
7 1/2
Hope it helped :)
Answer:
B
Step-by-step explanation:
y-2=-1/2(x+3)
Answer:
16
Step-by-step explanation:
3x + 4 = x + 12 [The straight line on the segments AB and BC indicate that they are the same length]
2x = 8 [Subtract x and 8 from both sides]
x = 4 [Divide both sides by two]
Length AB is equal to (3x + 4) as indicated by the diagram. Substituting x = 4, (3 * 4) + 4 = 16
