Answer:
<em>Answer: A) -8</em>
Step-by-step explanation:
The image shows the triangle where it can be noted that two of its sides are congruent (according to the tick marks). This forms an isosceles triangle that also has two congruent angles as shown in the image below.
The other angle (2) has a measure of x+88.
The sum of the internal angles of the triangle must be 180°, thus:
x + 88 + 50 + 50 = 180
Simplifying:
x + 188 = 180
x = 180 - 188 = -8
x = -8
Answer: A) -8
Answer:
V = 1/6 s^3
Step-by-step explanation:
In general the formula for the volume of a pyramid is V = (1/3) b * h
What you are given here is
B = s^2
h = (1/2) s
Putting this into the formula for the pyramid you get
V = (1/3) * s^2 * (s/2) Combine like terms (the "s"s)
V = (1/3) * (1/2) * s^3
V = 1/6 s^3
A) a1=0 a2=9
b)m1=0 m2=5
c)r1=0 r2=1.25 or 5/4
-4/3
Slope of equation in the form y=mx+c is the m which is 3/4
For perpendicular lines
m1*m2=-1
m2=-1/m2
=-4/3
