If the lines px = 12 and 2x + qy = 10 intersects at (1 , 1), what is the value of p + q?

shusha [124]

Answer:

p + q = 20

Step-by-step explanation:

Given the lines intersect at (1, 1 ) then x = 1 and y = 1 make the equations true.

Consider

px = 12 with x = 1

p = 12

Consider

2x + qy with x = 1 and y = 1

2 + q = 10 ( subtract 2 from both sides )

q = 8

Hence p + q = 12 + 8 = 20

Answer:

Therefore,

$AB=16.25\ units$

The Measurement of AB is 16.25 units.

Step-by-step explanation:

In Right Angle Triangle ABC

m∠C=90°

AC = 10.01 .....(Adjacent Side to angle A)

m∠A=52°

cos 52 ≈ 0.616

To Find:

AB = ? (Hypotenuse)

Solution:

In Right Angle Triangle ABC, Cosine Identity,

$\cos A= \dfrac{\textrm{side adjacent to angle A}}{Hypotenuse}\\$

Substituting the values we get

$\cos 52= \dfrac{AC}{AB}=\dfrac{10.01}{AB}$

But cos 52 ≈ 0.616 ....Given

$AB=\dfrac{10.01}{0.616}=16.25\ units$

Therefore,

$AB=16.25\ units$

The Measurement of AB is 16.25 units.
