Answer:

B) Line 2

using the formula:

$\sf c^2 = a^2 + b^2 -2abcos(C)$

$\sf c^2 = 14^2 + 8^2 -2(14)(8)cos(80)$

$\sf c^2 = 196 + 64 -244 *0.173$

$\sf c^2 = 221.1$

$\sf \sqrt{c} = \sqrt{221.1}$

$\sf c = 14.87$

∠F and ∠G are supplementary angles. If m∠F is two less than six times the measure of ∠G, find the measures of both angles

Mnenie [13.5K]

Answer:

∠ G = 26°, ∠ F = 154°

Step-by-step explanation:

Express ∠ F in terms of ∠ G, that is

F = 6G - 2

and since the angles are supplementary, then

G + 6G - 2 = 180, that is

7G - 2 = 180 ( add 2 to both sides )

7G = 182 ( divide both sides by 7 )

G = 26

Thus

∠ G = 26° and ∠ F = 6(26) - 2 = 156 - 2 = 154°

What is the value of x in the <br> triangle?

Makovka662 [10]

Answer:

x = 75°

Step-by-step explanation:

Sum of angles in a triangle: 180°

So,

50°+55°+x=180°

105°+ x = 180°

Subtract 105° from both sides

x = 75°
