Help with question 1 please

Alex Ar [27]

Answer:

Opposite angles of a parallelogram are congruent:

So: 124 = 2u, and u = 62 degrees.

Adjacent angles o f a parallelogram add to 180 degrees:

So: 124 + (v-3) = 180, and 121 + v = 180, meaning v = 59 degrees.

Let me know if this helps!

Which inequality correctly compares One-third, Five-sixths, and Three-fifths? One-third < Three-fifths < Five-sixths One-t

lilavasa [31]

Answer:

$\frac{1}{3} \: < \: \frac{3}{5} \: < \: \frac{5}{6}$

Step-by-step explanation:

We want to compare the fractions

$\frac{1}{3}, \frac{5}{6} , \frac{3}{5}$

First, we collect LCM

The LCM of 3,6, and 5 is 30

$\frac{1}{3} = \frac{10}{30} , \\ \frac{5}{6} = \frac{25}{30} , \\ \frac{3}{5} = \frac{18}{30}$

$\frac{10}{30} , \frac{18}{30} , \frac{25}{30}$

This means that

$\frac{1}{3} , \frac{3}{5} , \frac{5}{6}$

Hence,

$\frac{1}{3} \: < \: \frac{3}{5} \: < \: \frac{5}{6}$

Rearrange the formula a^2 + b^2 = c^2 for a.

diamong [38]

First, subtract the term b^2 from the both sides of the equation to isolate a^2. Then, take the square root of both sides of the equation so "a" is completely isolated. And voila! You should have the simplified version of this formula.

Rays QR and QS are tangents to circle P at R and S. If Q measures to 54°, find RS

Ainat [17]

Answer: $126^{\circ}$

Step-by-step explanation:

If we draw RP and PS, then in the quadrilateral formed, we know that $\angle PRQ=\angle PSQ=90^{\circ}$ , and since angles in a quadrilateral add to 360 degrees, this means $\angle SPR=126^{\circ}$ .

Thus, arc RS also measures 126 degrees
