The slopes of perpendicular line segments are 1/3 and d/5. What is the value of d

1 answer:

4 0

If 2 lines (or line segments) are perpendicular, then the product of their slopes is equal to -1.

Thus, since the given line segments are perpendicular, we have:

$\displaystyle{ \frac{1}{3}\cdot \frac{d}{5}=-1$ .

Multiplying both sides of the equation by 15, we get d=-15.

Answer: d=-15

Find the measure of the missing angle.<br> 77°

Georgia [21]

Answer: The missing angle is 13°

Step-by-step explanation:

Let ∠B

be the missing angle.

Let ∠A

be the angle that measures

77∘Let ∠C

the right angle that measures

90∘

The following is true of all triangles:

∠A+∠B+∠C=180∘

Express the above equation as

∠B

in terms of the other angles:

∠B=180∘−∠A−∠C

Substitute the values for ∠A and ∠C

∠B=180∘−77∘−90∘

∠B=13∘

What is the Quadratic formula

REY [17]

The quadratic formula is one of the ways to find a solution to the quadratic equation, alongside graphing and completing the square. The quadratic formula can be represented as $x= \frac{-b \sqrt{ b^{2}-4ac } }{2a}$ where a is the squared value, b is the multiplied value, and c is the constant.
