I believe the triangles are not similar. In order for the triangles to be similar, they would either need one more set of sides or angles to be congruent, but they only have one set of angles and one set of sides congruent. I am not entirely sure I am correct
Answer:
r=9
Step-by-step explanation:
We can use the Pythagorean to solve, since this is a right triangle
The leg lengths are r and 12
The hypotenuse is (r+6)
a^2 + b^2 = c^2
r^2 + 12^2 = (r+6)^2
Foiling out the right hand side
(r+6)(r+6_ = r^2+6r+6r+36
r^2 +144 = r^2 +12r+36
Subtracting r^2 from each side
r^2-r^2 +144 = r^2-r^2 +12r+36
144 = 12r+36
Subtract 36 from each side
144-36 = 12r+36-36
108 = 12r
Divide each side by 12
108/12 = 12r/12
9=r
Answer:
1,225
Step-by-step explanation:
you mutuply the sides
It would be, 5+(-7) = 5-7 = -2
B)Option B is your answer........
1. If it is not raining, then I will not carry an umbrella.
2. If two perpendicular lines do not intersect, then they do not form four 90° angles.
3. If <EAD is 80°, then that means <DAB is 100°, because they equal 180°.
4. A pair of congruent angles are <EAC and <DAB
