The interior angles of any triangle always sum to 180°.

In the triangle, angles C and D are labeled congruent, so the missing angle has measure

180° - 2 (6x - 5)°

This angle is supplementary to the one labeled (11x + 1)°, which means

180° = (11x + 1)° + (180° - 2 (6x - 5)°)

Solve for x :

180° = (11x + 1)° + 180° - 2 (6x - 5)°

0 = (11x + 1)° - 2 (6x - 5)°

0 = (11x)° + 1° - (12x)° + 10°

(12x - 11x)° = 1° + 10°

x° = 11°

x = 11

422 8/100 fraction notation

Ivenika [448]

The rule to convert a mixed fraction to an improper fraction is

$a\frac{b}{c} =\frac{(a)(c)+b}{c}$

Here in $422\frac{8}{100}$

Here a = 422, b = 8 and c = 100

Now a × c = 422 × 100 = 42200

And 42200 + 8 = 42208

So we have

$422\frac{8}{100} =\frac{(422)(100)+8}{10}=\frac{42200+8}{100}=\frac{42208}{100}$

This fraction can also be reduced as

$\frac{42208}{100}=\frac{10552}{25}$

Hence

$422\frac{8}{100}=\frac{42208}{100}=\frac{10552}{25}$
