Answer:
the second one
Step-by-step explanation:
when you multiply 2 negative numbers they turn into a positive
15/-5=-3
The area of the triangular base is
A = (1/2)bh
A = (1/2)(5 units)(12 units)
A = 30 units²
The "height" of the prism is 6 units, so the volume is
V = (area of base)×(height)
V = (30 units²)×(6 units)
V = 180 units³
The appropriate choice is
A. 180 units³
Decrease
The exterior angles of a polygon add up to 360 degrees, so the measure of each exterior angle of an n-sided regular polygon is given by 360/n. As n increases, 360/n will decrease.
Answer:
I think they are Similar Triangles
Step-by-step explanation:
Answer:
70
Step-by-step explanation:
we have the angle of vertex in the isosceles triangle = 180-2*bottom coner= 180-65/2=50
3 angles in the equilateral triangle are equal to 60
we have 50 + 60 +h =the angle of PQR =180
h=70
