Answer:
264 degree angle
Step-by-step explanation:
<u>Let's consider the facts at hand</u>:
- By Vertical Angle Theorem ⇒ ∠BCE = ∠DCF
- ∠BEC = ∠DFC
- Sides BE = DF
<u>Based on the diagram, triangles BCE and triangles DCF are similar</u>
⇒ based on the Angle-Angle theorem
⇒ since ∠BCE = ∠DCF and ∠BEC = ∠DFC
⇒ the two triangles are similar
Hope that helps!
<em>Definitions of Theorem I used:</em>
- <u><em>Vertical Angle Theorem: </em></u><em>opposite angles of two intersecting lines must be equal</em>
- <u><em>Angle-Angle Theorem:</em></u><em> if two angles of both triangles are equal, then the given triangles must be similar</em>

Answer:
is closest to the total surface area of the box
Step-by-step explanation:
we know that
The surface area of the box is equal to
where
B is the area of the base
P is the perimeter of the base
H is the height of the box
we have
<em>Find the area of the base B</em>
<em>Find the perimeter of the base P</em>
<em>Find the surface area</em>
Answer:
26.2
Step-by-step explanation:
PQ/QR = 8/16 = 0.5
tan(26.6) = 0.5
I'm confused too but that what i got
