Answer:
(b) √55
Step-by-step explanation:
The right triangles in this geometry are all similar, so the ratio of long side to short side is the same:
y/5 = 11/y
y² = 55 . . . . . . multiply by 5y
y = √55 . . . . . take the square root
__
And x=4√5 by looking at ratios of short side to hypotenuse.
Answer:
A = 60
B = 30
Step-by-step explanation:
Complementary angles add to 90 degrees
A = 2B A is twice the measure of B
A + B =90 Complementary angles add to 90 degrees
Substitute the first equation in for the second
A+B =90
2B+B=90
Combine like terms
3B = 90
Divide by 3
3B/3 = 90/3
B = 30
A = 2B
A = 2*30
A = 60
The correct answer is exactly one triangle
