Answer:131.78
Step-by-step explanation:
Answer:
m<A = 69°
m<C = 69°
Step-by-step explanation:
From the question given above, the following data were obtained:
AB = AC
m<B = 42°
m<A =?
m<C =?
Since:
AB = AC
Therefore,
m<A = m<C
A + B + C = 180 (sum of angles in a triangle)
C + 42 + C = 180
Collect like terms
C + C = 180 – 42
2C = 138
Divide both side by 2
C = 138 / 2
C = 69°
Finally, we shall determine m<A. This can be obtained as follow:
m<A = m<C
m<C = 69°
Therefore,
m<A = 69°
Answer:
Option D is correct.

Step-by-step explanation:
Power of product property:
Let the equation: 
Using power of products Property on given equation:
= 
Therefore, the only option D of an equation which shows the correct use of power of Products property is, 
Slope intercept form
y=mx+b
where the slope is m and b is the y intercept
the slope is needed
slope between (x₁,y₁) and (x₂,y₂) is (y₂-y₁)/(x₂-x₁)
so,
given (4,5) and (8,9)
the slope is (9-5)/(8-4)=4/4=1
y=1x+b
find b
input a point
(4,5)
x=4 and y=5
5=1(4)+b
5=4+b
minus 4 both sides
1=b
y=1x+1 is slope intercept form
I believe there are 210 blue counters in the bag im not sure but this is how i got this.
a whole will =1
1-.3=.7
there are 90 blue counters in .3 and there are 2.33333(repeat) in .7
so i multipled 2.3333(repeat) by 90. 2.3333(repeat)*90=210
-hope i got it right and that this helps-
p.s. i know it was confusing i have a very different way of thinking, lol.
