Answer:
Angle A is F Angle A = 57. 52+71=123. 180-123=57
Answer:190
Step-by-step explanation:
area of triangles is 5*3=15
15+15=30
rectangles are (5*10)*2+(6*10)=160
160+30=190
Step-by-step explanation:
If x = the amount of 12% and y = the amount of 20%, then x + y = 80
Since we need 80 grams of 15%, 80(.15) = 12.
We are given that .12x + .20y = 12.
We can solve the first equation for x or y. Let's do x.
x = 80 - y
.12(80 - y) + .20y = 12
9.6 - .12y + .20y = 12
.08y = 2.4
y = 30
x = 80 - 30 = 50
