Answer:

x = 17
y = 26

Step-by-step explanation:

In the left problem, you use the fact that <em>the sum of the segment lengths is equal to the overall length</em>.

AC +CB = AB

(3x -4) +(x -2) = 62

4x -6 = 62 . . . . . collect terms

4x = 68 . . . . . . . add 6

x = 17 . . . . . . . . . . divide by 4

In the right problem, you use the fact that <em>the sum of the angles is equal to the overall angle</em>. Here, that overall angle is a linear angle, so measures 180°.

∠DFG +∠GFE = ∠DFE

(5y +3) +(2y -5) = 180

7y = 182 . . . . . . . . . . . . . . collect terms, add 2

y = 26 . . . . . . . . . . . . . . . .divide by 7

If the smallest angle of a triangle is 20° and it is included between sides of 4 and 7, then (to the nearest tenth) the smallest

lawyer [7]

Answer:

$3.5$

Step-by-step explanation:

The smallest side of a triangle is formed by the smallest angle in the triangle.

To find the side opposite (formed by) the 20 degree angle, we can use the Law of Cosines. The Law of Cosines states that for any triangle, $c^2=a^2+b^2-ab\cos \gamma$ , where $a$ , $b$ , and $c$ are the three sides of the triangle and $\gamma$ is the angle opposite to $c$ .
