we know that

The measurement of <u>the external angle</u> is the semi-difference of the arcs it includes.

In this problem

$21\°=\frac{1}{2}[arc\ RU-arc\ SU]$

Solve for the measure of arc SU

$42\°=[arc\ RU-arc\ SU]$

$arc\ SU=arc\ RU-42\°$

$arc\ SU=119\°-42\°=77\°$

therefore

the answer is

The measure of the arc SU is $77\°$

Find the value of the variable y, where the sum of the fractions 6/(y+1) and y/(y-2) is equal to their product.

Blizzard [7]

Answer:

The answer is

$y = 3$

$y = - 4$

Step-by-step explanation:

We must find a solution where

$\frac{6}{y + 1} + \frac{y}{y - 2} = \frac{6}{y + 1} \times \frac{y}{y - 2}$

Consider the Left Side:

First, to add fraction multiply each fraction on the left by it corresponding denomiator and we should get

$\frac{6}{y + 1} \times \frac{y - 2}{y - 2} + \frac{y}{y - 2} \times \frac{y + 1}{y + 1}$

Which equals

$\frac{6y - 12}{(y -2) (y + 1)} + \frac{ {y}^{2} + y }{(y - 2)(y + 1)}$

Add the fractions

$\frac{y {}^{2} + 7y - 12 }{(y - 2)(y + 1)} = \frac{6}{y + 1} \times \frac{y}{y - 2}$

Simplify the right side by multiplying the fraction

$\frac{6y}{(y + 1)(y + 2)}$

Set both fractions equal to each other

$\frac{6y}{(y + 1)(y - 2)} = \frac{ {y}^{2} + 7y - 12}{(y + 1)(y - 2)}$

Since the denomiator are equal, we must set the numerator equal to each other

$6y = {y}^{2} + 7y - 12$

$= {y}^{2} + y - 12$

$(y + 4)(y - 3)$

$y = - 4$

$y = 3$

IRISSAK [1]

Answer: $3^1^1\\$

Step-by-step explanation:

$\frac{81^4}{3^5}$

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

The base is same power can be add or subtract

$3^1^6^-^5$

$3^1^1$
