9514 1404 393
Answer:
5) 112°
6) 40°
Step-by-step explanation:
5) The angle E or ? is half the sum of the intercepted arcs:
? = (130° +94°)/2 = 112°
__
6) The angle D is half the difference of the intercepted arcs:
? = (135° -55°)/2 = 40°
Answer:
AC/GI=BC/H
Step-by-step explanation:
we know that
The <u>Side-Angle-Side Similarity Theorem </u>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
In this problem the included angle is
∠C≅∠I
therefore
side AC must be proportional to side GI and side BC must be proportional to side HI
so
AC/GI=BC/HI
<em>Verify</em>
substitute the given values
15/9=20/12
15*12=20*9
180=180 -----> is true
therefore
The two sides are proportional
