If two triangles are similar, the correspondant sides are in proportion. So, the proportion is

$15\div 10 = 18 \div 12 = x \div 6$

A regular polygon

olga55 [171]

Answer:

3.6° = ext. angle

Step-by-step explanation:

For the shape to be a regular polygon, all interior angles must be congruent.

We can find every interior angle by using the formula:

$\frac{180(n-2)}{n}$

$\frac{180(100-2)}{100}$

$\frac{180(98)}{100}$

$\frac{17640}{100}$

176.4 = each int. angle

We also know that int. and ext. angles are supplementary!

180 = 176.4 - x

3.6° = ext. angle

Please Help:<br> In Δ ABC, sin A= 88, sin B= 42, and a =17 , find the length of b.

enyata [817]

Answer:

11.4 units

Step-by-step explanation:

a/sinA = b/sinB

17/sin(88) = b/sin(42)

b = sin(42) × 17/sin(88)

b = 11.3821540088
