Let a = the larger number
<span>b = the smaller number </span>
<span>a + b = 16 </span>
<span>3a - b = 72 </span>
<span>a = 16 - b </span>
<span>3(16 - b) - b = 72 </span>
<span>48 - 3b - b = 72 </span>
<span>-4b = 24 </span>
<span>b = -6 </span>
<span>a = 16 - (-6) </span>
<span>a = 22 </span>
<span>The two numbers are: </span>
<span>22 and -6</span>
Answer:
Obtuse isosceles
Step-by-step explanation:
Since this is an obtuse isosceles triangle, the two missing angles must be acute angles.
Answer:
∠B ≅ ∠Y △ABC ~ △ZYX by the SAS similarity theorem.
Step-by-step explanation:
1. 
units
units
units
units, then
2. 
and 
are right angles - given
3. 
two right angles are always congruent.
4. 
by SAS similarity theorem.
SAS Similarity Theorem states that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar.
