Find the equation of a line that is parallel to line g that contains (P, Q).
Fofino [41]

Correct option:

\boxed{x-y=P-Q}

<h2>Explanation:</h2>

Given that the line we are looking for is parallel to g, then the slope of that line and g is the same, therefore:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ (x_{1},y_{1})=(-3,2) \\ \\ (x_{2},y_{2})=(0,5) \\ \\ \\ m=\frac{5-2}{0-(-3)}=1

So we can write the point-slope form of the equation of the line as follows:

y-y_{0}=m(x-x_{0}) \\ \\ (x_{0},y_{0})=(P,Q) \\ \\ \\ y-Q=1(x-P) \\ \\ y-Q=x-P \\ \\ \\ Arranging: \\ \\ P-Q=x-y \\ \\ \boxed{x-y=P-Q}

If 2 of the angles of a triangle are 30 and 70 degrees, the third angle measures ...
Vedmedyk [2.9K]

Answer:

The third angle measures 80°

Step-by-step explanation:

Let us solve the question

In any triangle

∵ The sum of the measures of the interior angles of a triangle is 180°

∵ The angle of triangles are ∠1, ∠2, and ∠3

∴ m∠1 + m∠2 + m∠3 = 180°

∵ Two of the angles of the triangle are 30° and 70°

∴ m∠1 = 30°

∴ m∠2 = 70°

→ Substitute them in the rule above

∴ 30° + 70° + m∠3 = 180°

→ Add the like terms

∵ (30 + 70) + m∠3 = 180

∴ 100 + m∠3 = 180

→ Subtract 100 from both sides

∵ 100 - 100 + m∠3 = 180 - 100

∴ m∠3 = 80°

∴ The third angle measures 80°

En una empresa se realizan dos descuentos sucesivos : el primero del 30% y luego otro del 10% para la venta de sus artículos ¿ c
FromTheMoon [43]

If a company makes two discounts with one being made first and then another, the equivalent discount is 37%.

<h3>What was the equivalent discount?</h3>

Assume that the price of a good in the company was $10.

The initial discount of 30% takes the price to:

= 10 x ( 1  - 30%)

= $7

Then there is a 10% discount:

= 7 x (1 - 10%)

= $6.30

The equivalent discount is:

= (10 - 6.3) / 10

= 37%

WILL GIVE BRAINLIEST ASAP<br> In the figure below, m Z2 =55° and m 2 KJL = 154º.<br> Find m 21.
Elan Coil [88]

Answer:

99°

Explanation:

given:

m∠2 = 55°

solve:

m∠1 +  m∠2 = ∠KJL

m∠1 = ∠KJL - m∠2

m∠1 = 154° - 55°

m∠1 = 99°
