Answer:
D 5
Step-by-step explanation:
the same scaling factor s applies to all sides when transforming from the small to the large triangle.
x×s = x + 5
(x-2)×s = x +1
=> s = (x+5)/x
=> (x-2)×(x+5)/x = x + 1
=> x² + 3x - 10 = x² + x
=> 3x - 10 = x
=> 2x = 10
=> x = 5
Answer:
Pythagorean Theorem and Sine
Step-by-step explanation:
you could use pythagorean theorem to find the 3rd side, then use inverse sine of c.
Using the equation a2 + b2 = c2
Subtract 13squared from 5squared
169-25
then take the square root of the answer- which is 12
then do the inverse of sine
that should give you the missing angle
Use mathway on Google. it will give you the answer.
