Answer:
7/11
Step-by-step explanation:
Acc. to midpoint theorem,
15={(2x+9) + (4x-15)}/2
⇒ 30=2x+9+4x-15
⇒ 30-9+15=6x
⇒ 36/6=x
⇒6=x
WZ= 4x-15
=4*6-15
=24-15=9
Answer:
x = 78º
y = 35º
Step-by-step explanation:
These are isosceles triangles
two angles are congruent
-----------------------------
x + 51 + 51 = 180
x = 180 - 102
x = 78º
y + y + 110 = 180
2y = 70
y = 35º
Answer:
x=-9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−6(x+1)−18=26+4
(−6)(x)+(−6)(1)+−18=26+4(Distribute)
−6x+−6+−18=26+4
(−6x)+(−6+−18)=(26+4)(Combine Like Terms)
−6x+−24=30
−6x−24=30
Step 2: Add 24 to both sides.
−6x−24+24=30+24
−6x=54
Step 3: Divide both sides by -6.
−6x
−6
=
54
−6
x=−9
Answer:
x=−9
This is a triangular prism.
The lateral faces are triangles; this means that the two bases are parallel to one another. This makes it a prism instead of a pyramid.
The bases being triangles makes it a triangular prism.
