Answer:

$b = 17$

Step-by-step explanation:

For this triangle we have to

$a=18.2\\B=62\°\\C=48\°$

We want to find the length of b

We know that the sum of the internal angles of a triangle is 180 °

$A + 62 +48=180\\\\A=180-62-48\\\\A=70\°$

Now we use the sine theorem to find the length of b:

$\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}$

Then:

$\frac{sin(A)}{a}=\frac{sin(B)}{b}\\\\b=\frac{sin(B)}{\frac{sin(A)}{a}}\\\\b=a*\frac{sin(B)}{sin(A)}\\\\b=(18.2)\frac{sin(62)}{sin(70)}\\\\b=17$

Find the sum : 3/8 + 22.5

rewona [7]

Answer:
183/8 or 22.875

Step-by-step explanation:

Take 22.5 and put it over 1 so 22.5/1

And then multiply by 8 to get a common denominator (180/8) then add the 3/8 and you get 183/8 or 22.875

Answer: (D) 9

Step-by-step explanation:

This is an isosceles triangle. Since the legs are congruent, then the base angles are congruent.

9x + 3 = 84

- 3 -3

9x = 81

÷9 ÷9

x = 9
