Answer:
A= 56
E= 59
Step-by-step explanation:
All triangle are 180 degrees so
A.
71 + 53 = 124
180- 124 = 56
B.
70 + 51 = 121
180 - 121 = 59
Hope this helps
<span>There are two possible ways where you can express this. First, is by presenting the equation net of 5 percent which is "x=1.0355n+2.6505m". The other way to express such is by presenting it with gross amount which is "x= (1-0.05)(1.09n+2.79m)"
</span>
Okay, so all the angles of the triangle will add up to 180
You know one side is 104 and the other two are equal to each other.
180-104= 76
76 is both of the angles together so divide it by two to get 38
X=38

Answer choice A. The function moves left 4 units, and 2 units up.
<span>Dr. Graham currently has two acid solutions.
60% acid AND 20% acid </span>
Dr. Graham needs 30 L of a 50% acid solution
We set up 2 equations in which s = 60% acid and t = 20% acid
A) s + t = 30
B) .60s + .20t = (.50 * 30)
We multiply equation A by -.20
A) = -.20s -.20t = -6 then we add it to B)
B) .60s + .20t = 15
.40s = 9
s = 22.5
t = 7.5
So, she needs to mix 22.5 liters of 60% acid with 7.5 liters of 20% acid.
