Find the value of x in the triangle shown below.

Alekssandra [29.7K]

Answer:

102 degrees.

Step-by-step explanation:

Because the 3.3's are congruent (the same), this triangle is isosceles.

A property of isosceles means that the two angles are congruent.

39+39= 78

This means that the last angle must be 180-78.

nataly862011 [7]

Answer:

$L=\frac{15}{16}\ yd$

Step-by-step explanation:

<u><em>The correct question is</em></u>

Devon needs a wood board with an area of 5/16 square yard to complete a project. If the wood board is 1/3 yard wide, how long must the board be?

we know that

The area of a rectangle is equal to

$A=LW$

where

L is the length

W is the width

we have

$A=\frac{5}{16}\ yd^2\\\\W=\frac{1}{3}\ yd$

substitute

$\frac{5}{16}=L(\frac{1}{3})$

solve for L

$L=\frac{5}{16}(3)$

$L=\frac{15}{16}\ yd$
