Answer:
<h2>462</h2>
Step-by-step explanation:
15% of 840 is 126
30% of 840 is 252
252
<u>+ 126 </u>
<em> 378</em>
<em></em>
840 - 378 = <em>462</em>
or

X= -8 that uis your answer for that question :)
If triangles are congruent then, their corresponding sides and angles should have the same measurement. From the given, STU is congruent to VWX, angle S, T, U should be congruent to angles V, W, and X, respectively. From the choices, the answer should be letter D. because U and V do not appear in the same order from both names.
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
