Answer:
28 degrees
Step-by-step explanation:
152 is the exact same measure as angle 2.
To get to 180 you have to add 152 + angle 1
Angle one is the same as angle 3.
180 - 152 = 28

All you have to do is divide 20 by 12.5
1.25 divided by 8 =0.15635×100=15.6% or round up to 16%
The given triangle is isosceles, so the two remaining angles in the triangle both have measure <em>xº</em>. The interior angles of any triangle sum to 180º, so that
58º + <em>xº</em> + <em>xº</em> = 180º
58 + 2<em>x</em> = 180
2<em>x</em> = 122
<em>x</em> = 61
Angles <em>y</em> and <em>z</em> are supplementary to angle <em>x</em>, so that
<em>xº</em> + <em>yº</em> = 180º
and
<em>xº</em> + <em>zº</em> = 180º
and consequently, <em>y</em> = <em>z</em>. In particular, we get
<em>y</em> = 180 - 61
<em>y</em> = 119
and so
<em>z</em> = 119
