Answer:
r = 2
Step-by-step explanation:
I'm assuming we're finding r
11 = 1 + 3r + 2r
Add up the numbers with r
11 = 1 + 5r
Subtract both sides by 1
11 = 1 + 5r
-1 -1
10 = 5r
Divide both sides by the coefficient, 5, to isolate the variable, r
10/5 = 5r/5
r = 2
Answer:
d= 99 e= 81 f= 99
Step-by-step explanation:
(x+51)+(x+59)+84=180 (Sum of angles in a triangle)
2x= 180-194= -14
x=-7
Angle A: x+51=-7+51=44°
These triangles are congruent because of SAS so therefore 3x-5 =2x+1 and x=6
