W + 3w - 5 = 23 +5 +5 (-5 +5 cancels out and equals 0) Like terms. What you do to one side, you do to the other. 4w = 28 ---- --- 4 4 Isolate w by dividing by 4 W = 7

V=448 in^3
l=8 in
w=12
h=?
V=l•w•h/3
448=8•12•h/3 multiply both sides by 3
3•448=96•h
1344=96•h
h=1344/96
h=14 in


V=l•w•h/3
h=4in
l=3in
w=2.5 in
V=?
V=4•3•2.5/3
V=30/3
V=10 in^3

Answer:

x=75°and y=x= 75°

Step-by-step explanation:

Reason: opposite angles are equal and how I got 75 is by drawing an extension line and finding the other angle (i.e. angle on a straight line=180) so 180-105=75.

What is the height of an isosceles trapezoid, if the lengths of its bases are 5m and 11m, and the length of a leg 4m? (Please sh
Ivan

We have been given the measure of two parallel sides as 11 m and 5 m. And we are given one of the slanted sides as 4 m.

From the given information, we can find the base of one of the side triangles as 3 m.

Therefore, upon using Pythagorean theorem, we get the set up for height as

h^{2}=4^{2}-3^{2}=7

h=\sqrt{7}

Therefore, height of the required figure is \sqrt{7} m
