The question gives you 4 different numbers that could be x, so you have to replace each x in each problem and solve. If the two answers are equivalent, that is your answer. For the first one, 6 times 2 is 12, minus 2 is 10. 5 times 2 is 10, plus 3 is 13. 10 is not equal to 13, so that is not the answer. For 5, 6 times 5 is 30, minus 2 is 28. 5 times 5 is 25, plus 3 is 28, so therefore the answer is x=5

The vertex angle of an isosceles triangle measures 26° . The base is 30 units long. What is the length of a leg of the isosceles

sergejj [24]

Answer:

65.46 units

Step-by-step explanation:

Given the information:

The vertex angle of an isosceles triangle measures 26°

=> the leg angle is:

= (180° - 26° )/2

= 77°

The base is 30 units

Let x is the length of the leg side (x>0)

We use cosine law to find x, we have:

$30^{2}$ = $x^{2} +x^{2} -2xxCos(26)$ Because the isosceles has two equal leg sides

<=> $30^{2}$ = 2 $x^{2}$ - 1.79 $x^{2}$

<=> 0.21 $x^{2}$ = $30^{2}$

<=> $x^{2} =4285$

<=> x = 65.46 units

Hope it will find you well.

What is the value of m? 1 _m =12-m 3

alexdok [17]

$\bf \cfrac{1}{3}m=12-m\impliedby \textit{now, if we multiply both sides by }3
\\\\\\
\boxed{3}\cdot \cfrac{1}{3}m=\boxed{3}\cdot 12-\boxed{3}\cdot m\implies m=36-3m\implies 4m=36
\\\\\\
m=\cfrac{36}{4}\implies m=9$
