Answer:
59
Step-by-step explanation:
all triangles add up to 180 degrees.
add 87+34=121
do 180-121=59 because you want to find the value of x
to check your work add up all of the degrees together and when you get 180 you will be correct!

Her we know that Jacey wrote an equation to find an angle measure. The equation is as follows:
![\frac{360^{\circ}}{a}=b](https://tex.z-dn.net/?f=%5Cfrac%7B360%5E%7B%5Ccirc%7D%7D%7Ba%7D%3Db)
So, if the angle 360° is a central angle, that is, an angle between two radii in a circle, then:
<em>a: Represents the number of equal parts parts the circle is divided</em>
<em>b: Represents the measure of the central angle of each part</em>
For example, suppose you have a circle and want to divide it into six parts, then, the central angle of each part of the circle will measure 60 degrees as indicated in the figure below.
