Answer:
volume= 1040
surface area=696
Step-by-step explanation:
1/2x 13x10x16
=1040#
(1/2x12x10)2
=120
(16x13)2
=416
16x10
=160
120+426+160
=696#
The answer:
we observe that <span>m∠DBC = 130°
</span><span>
we should find the value of </span>mEDB to answer this question
Angle ABC is a straight angle, so m ABC= 180°, but
mABD + <span>m∠DBC = 180° (look at the figure)
</span>
so mABD= 180° - m∠DBC = 180 - 130 = 50°
therefore, mABD= 50°,
and BE bisects ∠ABD imiplies mEBA = mEDB, and mABD= mEBA + mEDB= 50°, it does mean 2x mEBA = 50°
and from where mEBA = 50°/2=25°
Okay since x= -6, we have to plug it in everywhere it says x.
-6^2-6/-6-4
30/-10
The answer to this is -3 .
