Answer:
segment a = 12
Step-by-step
2 transversal lines will create similar figures. this means that by doing
a/20= 9/15, you can calculate the length of segment a since they will be similar
Answer:
Step-by-step explanation:
Here the coefficients of this quadratic equation are {7, -1, -3}. Note that the given equation must be rewritten in standard form: 7x^2 - x - 3.
Then the discriminant, b^2 - 4ac, is (-1)^2 - 4(7)(-3), or 1 + 84, or 85. Because this discriminant is positive, the given quadratic has two real, unequal roots. These roots are:
-(-1) ± √85
x = ------------------
14
or:
1 ± √85
x = ------------------
14
39.8°
Step-by-step explanation:
theta = tan^-1(10/12)
