In the diagram below, mpr = 140 and mqs = 106. What is the measure of ptr?

choli [55]

Answer:

Option B

$m\angle PTR=123^o$

Step-by-step explanation:

we know that

The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite

$m\angle PTR=\frac{1}{2}[arc\ PR+arc\ QS]$

substitute the given values

$m\angle PTR=\frac{1}{2}[140^o+106^o]$

$m\angle PTR=123^o$

If |u| = 10, |v| = 8, and the angle formed between them is 60°, then u · v = ?

Gre4nikov [31]

U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.

Answer:

x = 2, y = 4

Step-by-step explanation:

x + $\frac{3}{4}$ y = 5 ( multiply through by 4 to clear the fraction )

4x + 3y = 20 → (1)

x - $\frac{1}{2}$ y = 0 ( multiply through by 2 to clear the fraction )

2x - y = 0 → (2)

Multiplying (2) by 3 and adding to (1) will eliminate y

6x - 3y = 0 → (3)

Add (1) and (3) term by term to eliminate y

10x + 0 = 20

10x = 20 ( divide both sides by 10 )

x = 2

Substitute x = 2 into either of the 2 equations and solve for y

Substituting into (1)

4(2) + 3y = 20

8 + 3y = 20 ( subtract 8 from both sides )

3y = 12 ( divide both sides by 3 )

y = 4

Solution is x = 2, y = 4
