The picture in the attached figure

we know that
<span>The base of a solid oblique pyramid is an equilateral triangle with a base edge length of 14 units
so
AC=CD=AD=14 units

in the right triangle ABC
tan A=opposite side angle A/adjacent side angle A
opposite side angle A=BC
adjacent side angle A=AC
angle A=45 degrees
so
tan 45=BC/14------------> BC=14*tan 45-------> BC=14*1-----> BC=14 units

the answer is
</span><span>the height of the pyramid is 14 units (BC)</span>

When twice a number is subtracted from 29 the result is 21 find the number
Gre4nikov [31]
X= a number

29 - 2x= 21
subtract 29 from both sides
-2x= -8
divide both sides by -2
x= 4

CHECK:
29 - 2x= 21
29 - 2(4)= 21
29 - 8= 21
21= 21

ANSWER: The number is 4.

Hope this helps! :)

Fourth test mark should be 86

85 + 82 + 75 + 86 = 328
328 divide by 4 (as there are four tests) = 82

Based on the information marked in the diagram, ABC and DEF must be congruent.
drek231 [11]

Answer:

Option A is correct

True, ΔABC and ΔDEF must be congruent.

Explanation:

LA theorem or Postulates states that given two right triangles,  where one acute angle and a leg of one of the triangles are congruent to  an angle and a leg of the other triangle, then the two triangles are congruent.

In  ΔABC and ΔDEF

AB = DE              [Leg]                [Given in the figure]

\angle BAC = \angle EDF = 90^{\circ}     [Given]

\angle BCA = \angle EFD   [Acute angle]        [Given in the figure]

Then, by the LA theorem or Postulates;

therefore, ΔABC \cong ΔDEF .
