Greatest common factor is the best way to simplify fractions. For instance, 20/100 has a common factor of 5, which would give you the fraction, 4/20, but 20/100 also has a common factor of 20, which is the greatest common faction, leaving you the fraction 1/5

Answer:

x = $\sqrt{164$

Step-by-step explanation:

In order to find the hypothenuse, you need to do $8^{2} + 10^{2}$ . Which equals 164. Therefore, since $a^{2} +b^{2} =c^{2}$ , a=8, b=10, and c= $\sqrt{164$ .

The ratio of the measures of the three angles in a tangle 3107. Find the measures of the angles and write them in size order,

N76 [4]

Answer:

27, 90 and 63

Step-by-step explanation:

Given

Ratio of triangle sides

$Ratio = 3 : 10 : 7$

Required:

The length of each side

Triangles in a triangle add up to 180.

The side with ratio 3 is:

$S_1 = \frac{3}{3 + 10 + 7} *180$

$S_1 = \frac{3 *180}{20}$

$S_1 = \frac{540}{20}$

$S_1 = 27$

The side with ratio 10 is:

$S_2 = \frac{10}{3 + 10 + 7} *180$

$S_2 = \frac{10 *180}{20}$

$S_2 = \frac{1800}{20}$

$S_2 = 90$

Lastly:

The side with 7 as its ratio

$S_3 = \frac{7}{3 + 10 + 7} *180$

$S_3 = \frac{7 *180}{20}$

$S_3 = \frac{1260}{20}$

$S_3 = 63$

Hence, the angles are: 27, 90 and 63
