We need to look at 2 similar triangles
1) big one: legs - a,b, and hypotenuse - c
2)small one: legs - h,s, and hypotenuse - b.
Corresponding sides:
hypotenuse - c and hypotenuse - b,
big leg - b and big leg - s,
small leg - a, and small leg h.
?(/b(big leg, big triangle)= b(hypotenuse, small triangle )/s (big leg, small triangle)
? should be hypotenuse of the big triangle, c.
Answer is second one c.
Answer:
Step-by-step explanation:
Note that
sin135° = sin(180 - 135)° = sin45° = = 
Answer:
b
Step-by-step explanation:
The equation:

is in the form:
a

x
+
c
=

with
a
=

,
b
=

,
c
=

The roots are given by the quadratic formula:

The answer would be positive 24. The reason being is because of the fact that two negatives when multiplied cancel the negative. Also 12 * 2 is 24 so yeah
