Answer:
75
Step-by-step explanation:
If the triangles are similar, it means the ratio between the two give sides is the same. As seen from the smaller triangle the ratio of the two top sides would be 16:50 or 8:25.
Since the first side of the bigger triangle (24) is three times 8 (it's ratio side), then the other side must be 3x25 = 75, which maintains the ratio 8:25 between the two sides (24:75).
Hope this helped!
Answer:
B
Step-by-step explanation:
Angle 4 × Angle 3 = 90
Complementary angles
11x + 4x = 90
15x = 90
x = 6
Angle 3 = 4x = 4(6) = 24°
Answer: It would be the second option.
Step-by-step explanation:
If angles 7 and 1 are supplementary, so are 5 and 1 because angle 7= angle 5. Supplements are not always equal. Imagine a more acute angle. One would be, say, 30, and the other would be 150. These numbers are different, so it would be the second option.
Y = -2x - 4
x + 4y = 19
x + 4(-2x - 4) = 19
x + (-8x) - 16 = 19
-7x - 16 = 19
-7x = 35
-x = 5
x = -5
y = -2x - 4
y = -2(-5) - 4
y = 10 -4
y = 6
Solution set {-5, 6} (C)
